agent: default the primary_datacenter to the datacenter if not configured (#7111)
Something similar already happens inside of the server
(agent/consul/server.go) but by doing it in the general config parsing
for the agent we can have agent-level code rely on the PrimaryDatacenter
field, too.

connect: check if intermediate cert needs to be renewed. (#6835)
Currently when using the built-in CA provider for Connect, root certificates are valid for 10 years, however secondary DCs get intermediates that are valid for only 1 year. There is no mechanism currently short of rotating the root in the primary that will cause the secondary DCs to renew their intermediates.
This PR adds a check that renews the cert if it is half way through its validity period.

In order to be able to test these changes, a new configuration option was added: IntermediateCertTTL which is set extremely low in the tests.

Expose HTTP-based paths through Connect proxy (#6446)
Fixes: #5396

This PR adds a proxy configuration stanza called expose. These flags register
listeners in Connect sidecar proxies to allow requests to specific HTTP paths from outside of the node. This allows services to protect themselves by only
listening on the loopback interface, while still accepting traffic from non
Connect-enabled services.

Under expose there is a boolean checks flag that would automatically expose all
registered HTTP and gRPC check paths.

This stanza also accepts a paths list to expose individual paths. The primary
use case for this functionality would be to expose paths for third parties like
Prometheus or the kubelet.

Listeners for requests to exposed paths are be configured dynamically at run
time. Any time a proxy, or check can be registered, a listener can also be
created.

In this initial implementation requests to these paths are not
authenticated/encrypted.

connect: introduce ExternalSNI field on service-defaults (#6324)
Compiling this will set an optional SNI field on each DiscoveryTarget.
When set this value should be used for TLS connections to the instances
of the target. If not set the default should be used.

Setting ExternalSNI will disable mesh gateway use for that target. It also 
disables several service-resolver features that do not make sense for an 
external service.

Pierre Souchay b4590fb8e8 Display nicely Networks (CIDR) in runtime configuration (#6029)
* Display nicely Networks (CIDR) in runtime configuration

CIDR mask is displayed in binary in configuration.
This add support for nicely displaying CIDR in runtime configuration.

Currently, if a configuration contains the following lines:

  "http_config": {
    "allow_write_http_from": [
      "127.0.0.0/8",
      "::1/128"
    ]
  }

A call to `/v1/agent/self?pretty` would display

  "AllowWriteHTTPFrom": [
            {
                "IP": "127.0.0.0",
                "Mask": "/wAAAA=="
            },
            {
                "IP": "::1",
                "Mask": "/////////////////////w=="
            }
  ]

This PR fixes it and it will now display:

   "AllowWriteHTTPFrom": [ "127.0.0.0/8", "::1/128" ]

Allow raft TrailingLogs to be configured. (#6186)
This fixes pathological cases where the write throughput and snapshot size are both so large that more than 10k log entries are written in the time it takes to restore the snapshot from disk. In this case followers that restart can never catch up with leader replication again and enter a loop of constantly downloading a full snapshot and restoring it only to find that snapshot is already out of date and the leader has truncated its logs so a new snapshot is sent etc.

In general if you need to adjust this, you are probably abusing Consul for purposes outside its design envelope and should reconsider your usage to reduce data size and/or write volume.

handle structs.ConfigEntry decoding similarly to api.ConfigEntry decoding (#6106)
Both 'consul config write' and server bootstrap config entries take a
decoding detour through mapstructure on the way from HCL to an actual
struct. They both may take in snake_case or CamelCase (for consistency)
so need very similar handling.

Unfortunately since they are operating on mirror universes of structs
(api.* vs structs.*) the code cannot be identitical, so try to share the
kind-configuration and duplicate the rest for now.

ui: modify content path (#5950)
* Add ui-content-path flag

* tests complete, regex validator on string, index.html updated

* cleaning up debugging stuff

* ui: Enable ember environment configuration to be set via the go binary at runtime (#5934)

* ui: Only inject {{.ContentPath}} if we are makeing a prod build...

...otherwise we just use the current rootURL

This gets injected into a <base /> node which solves the assets path
problem but not the ember problem

* ui: Pull out the <base href=""> value and inject it into ember env

See previous commit:

The <base href=""> value is 'sometimes' injected from go at index
serve time. We pass this value down to ember by overwriting the ember
config that is injected via a <meta> tag. This has to be done before
ember bootup.

Sometimes (during testing and development, basically not production)
this is injected with the already existing value, in which case this
essentially changes nothing.

The code here is slightly abstracted away from our specific usage to
make it easier for anyone else to use, and also make sure we can cope
with using this same method to pass variables down from the CLI through
to ember in the future.

* ui: We can't use <base /> move everything to javascript (#5941)

Unfortuantely we can't seem to be able to use <base> and rootURL
together as URL paths will get doubled up (`ui/ui/`).

This moves all the things that we need to interpolate with .ContentPath
to the `startup` javascript so we can conditionally print out
`{{.ContentPath}}` in lots of places (now we can't use base)

* fixed when we serve index.html

* ui: For writing a ContentPath, we also need to cope with testing... (#5945)

...and potentially more environments

Testing has more additional things in a separate index.html in `tests/`

This make the entire thing a little saner and uses just javascriopt
template literals instead of a pseudo handbrake synatx for our
templating of these files.

Intead of just templating the entire file this way, we still only
template `{{content-for 'head'}}` and `{{content-for 'body'}}`
in this way to ensure we support other plugins/addons

* build: Loosen up the regex for retrieving the CONSUL_VERSION (#5946)

* build: Loosen up the regex for retrieving the CONSUL_VERSION

1. Previously the `sed` replacement was searching for the CONSUL_VERSION
comment at the start of a line, it no longer does this to allow for
indentation.
2. Both `grep` and `sed` where looking for the omment at the end of the
line. We've removed this restriction here. We don't need to remove it
right now, but if we ever put the comment followed by something here the
searching would break.
3. Added `xargs` for trimming the resulting version string. We aren't
using this already in the rest of the scripts, but we are pretty sure
this is available on most systems.

* ui: Fix erroneous variable, and also force an ember cache clean on build

1. We referenced a variable incorrectly here, this fixes that.
2. We also made sure that every `make` target clears ember's `tmp` cache
to ensure that its not using any caches that have since been edited
everytime we call a `make` target.

When set at the check level, it can override the agent max for a specific check but
only if it is lower than the agent max.

Default value is 4k, and input must be at least 1.

R.B. Boyer cc1aa3f973 acl: adding Roles to Tokens (#5514)
Roles are named and can express the same bundle of permissions that can
currently be assigned to a Token (lists of Policies and Service
Identities). The difference with a Role is that it not itself a bearer
token, but just another entity that can be tied to a Token.

This lets an operator potentially curate a set of smaller reusable
Policies and compose them together into reusable Roles, rather than
always exploding that same list of Policies on any Token that needs
similar permissions.

This also refactors the acl replication code to be semi-generic to avoid
3x copypasta.

ACL Token Persistence and Reloading (#5328)
This PR adds two features which will be useful for operators when ACLs are in use.

1. Tokens set in configuration files are now reloadable.
2. If `acl.enable_token_persistence` is set to `true` in the configuration, tokens set via the `v1/agent/token` endpoint are now persisted to disk and loaded when the agent starts (or during configuration reload)

Note that token persistence is opt-in so our users who do not want tokens on the local disk will see no change.

Some other secondary changes:

* Refactored a bunch of places where the replication token is retrieved from the token store. This token isn't just for replicating ACLs and now it is named accordingly.
* Allowed better paths in the `v1/agent/token/` API. Instead of paths like: `v1/agent/token/acl_replication_token` the path can now be just `v1/agent/token/replication`. The old paths remain to be valid. 
* Added a couple new API functions to set tokens via the new paths. Deprecated the old ones and pointed to the new names. The names are also generally better and don't imply that what you are setting is for ACLs but rather are setting ACL tokens. There is a minor semantic difference there especially for the replication token as again, its no longer used only for ACL token/policy replication. The new functions will detect 404s and fallback to using the older token paths when talking to pre-1.4.3 agents.
* Docs updated to reflect the API additions and to show using the new endpoints.
* Updated the ACL CLI set-agent-tokens command to use the non-deprecated APIs.

Centralise tls configuration part 1 (#5366)
In order to be able to reload the TLS configuration, we need one way to generate the different configurations.

This PR introduces a `tlsutil.Configurator` which holds a `tlsutil.Config`. Afterwards it is responsible for rendering every `tls.Config`. In this particular PR I moved `IncomingHTTPSConfig`, `IncomingTLSConfig`, and `OutgoingTLSWrapper` into `tlsutil.Configurator`.

This PR is a pure refactoring - not a single feature added. And not a single test added. I only slightly modified existing tests as necessary.

New ACLs (#4791)
This PR is almost a complete rewrite of the ACL system within Consul. It brings the features more in line with other HashiCorp products. Obviously there is quite a bit left to do here but most of it is related docs, testing and finishing the last few commands in the CLI. I will update the PR description and check off the todos as I finish them over the next few days/week.
Description

At a high level this PR is mainly to split ACL tokens from Policies and to split the concepts of Authorization from Identities. A lot of this PR is mostly just to support CRUD operations on ACLTokens and ACLPolicies. These in and of themselves are not particularly interesting. The bigger conceptual changes are in how tokens get resolved, how backwards compatibility is handled and the separation of policy from identity which could lead the way to allowing for alternative identity providers.

On the surface and with a new cluster the ACL system will look very similar to that of Nomads. Both have tokens and policies. Both have local tokens. The ACL management APIs for both are very similar. I even ripped off Nomad's ACL bootstrap resetting procedure. There are a few key differences though.

    Nomad requires token and policy replication where Consul only requires policy replication with token replication being opt-in. In Consul local tokens only work with token replication being enabled though.
    All policies in Nomad are globally applicable. In Consul all policies are stored and replicated globally but can be scoped to a subset of the datacenters. This allows for more granular access management.
    Unlike Nomad, Consul has legacy baggage in the form of the original ACL system. The ramifications of this are:
        A server running the new system must still support other clients using the legacy system.
        A client running the new system must be able to use the legacy RPCs when the servers in its datacenter are running the legacy system.
        The primary ACL DC's servers running in legacy mode needs to be a gate that keeps everything else in the entire multi-DC cluster running in legacy mode.

So not only does this PR implement the new ACL system but has a legacy mode built in for when the cluster isn't ready for new ACLs. Also detecting that new ACLs can be used is automatic and requires no configuration on the part of administrators. This process is detailed more in the "Transitioning from Legacy to New ACL Mode" section below.

Pierre Souchay 251156eb68 Added SOA configuration for DNS settings. (#4714)
This will allow to fine TUNE SOA settings sent by Consul in DNS responses,
for instance to be able to control negative ttl.

Will fix: https://github.com/hashicorp/consul/issues/4713

# Example

Override all settings:

* min_ttl: 0 => 60s
* retry: 600 (10m) => 300s (5 minutes),
* expire: 86400 (24h) => 43200 (12h)
* refresh: 3600 (1h) => 1800 (30 minutes)

```
consul agent -dev -hcl 'dns_config={soa={min_ttl=60,retry=300,expire=43200,refresh=1800}}'
```

Result:
```
dig +multiline @localhost -p 8600 service.consul

* Test coverage for the new sidecarServiceFromNodeService method.

* Test API registratrion with SidecarService

* Recursive Key Translation 🤦

* Add tests for nested sidecar defintion arrays to ensure they are translated correctly

* Use dedicated internal state rather than Service Meta for tracking sidecars for deregistration.

Paul Banks b83bbf248c Add Proxy Upstreams to Service Definition (#4639)
* Refactor Service Definition ProxyDestination.

This includes:
 - Refactoring all internal structs used
 - Updated tests for both deprecated and new input for:
   - Agent Services endpoint response
   - Agent Service endpoint response
   - Agent Register endpoint
     - Unmanaged deprecated field
     - Unmanaged new fields
     - Managed deprecated upstreams
     - Managed new
   - Catalog Register
     - Unmanaged deprecated field
     - Unmanaged new fields
     - Managed deprecated upstreams
     - Managed new
   - Catalog Services endpoint response
   - Catalog Node endpoint response
   - Catalog Service endpoint response
 - Updated API tests for all of the above too (both deprecated and new forms of register)

TODO:
 - config package changes for on-disk service definitions
 - proxy config endpoint
 - built-in proxy support for new fields

* Agent proxy config endpoint updated with upstreams

* Config file changes for upstreams.

* Add upstream opaque config and update all tests to ensure it works everywhere.

* Built in proxy working with new Upstreams config

* Command fixes and deprecations

* Fix key translation, upstream type defaults and a spate of other subtele bugs found with ned to end test scripts...

TODO: tests still failing on one case that needs a fix. I think it's key translation for upstreams nested in Managed proxy struct.

* Fix translated keys in API registration.
≈

* Fixes from docs
 - omit some empty undocumented fields in API
 - Bring back ServiceProxyDestination in Catalog responses to not break backwards compat - this was removed assuming it was only used internally.

* Documentation updates for Upstreams in service definition

* Fixes for tests broken by many refactors.

* Enable travis on f-connect branch in this branch too.

* Add consistent Deprecation comments to ProxyDestination uses

* Update version number on deprecation notices, and correct upstream datacenter field with explanation in docs

Pierre Souchay eddcf228ea Implementation of Weights Data structures (#4468)
* Implementation of Weights Data structures

Adding this datastructure will allow us to resolve the
issues #1088 and #4198

This new structure defaults to values:
```
   { Passing: 1, Warning: 0 }
```

Which means, use weight of 0 for a Service in Warning State
while use Weight 1 for a Healthy Service.
Thus it remains compatible with previous Consul versions.

* Implemented weights for DNS SRV Records

* DNS properly support agents with weight support while server does not (backwards compatibility)

* Use Warning value of Weights of 1 by default

When using DNS interface with only_passing = false, all nodes
with non-Critical healthcheck used to have a weight value of 1.
While having weight.Warning = 0 as default value, this is probably
a bad idea as it breaks ascending compatibility.

Thus, we put a default value of 1 to be consistent with existing behaviour.

* Added documentation for new weight field in service description

* Better documentation about weights as suggested by @banks

* Return weight = 1 for unknown Check states as suggested by @banks

* Fixed typo (of -> or) in error message as requested by @mkeeler

* Fixed unstable unit test TestRetryJoin

* Fixed unstable tests

* Fixed wrong Fatalf format in `testrpc/wait.go`

* Added notes regarding DNS SRV lookup limitations regarding number of instances

* Documentation fixes and clarification regarding SRV records with weights as requested by @banks

* Rephrase docs

agent/config: add managed proxy upstreams config to skip
agent/config will turn [{}] into {} (single element maps into a single
map) to work around HCL issues. These are resolved in HCL2 which I'm
sure Consul will switch to eventually.

This breaks the connect proxy configuration in service definition FILES
since we call this patch function. For now, let's just special-case skip
this. In the future we maybe Consul will adopt HCL2 and fix it, or we
can do something else if we want. This works and is tested.

Pierre Souchay 0b7f620dc6 Allow to control the number of A/AAAA Record returned by DNS
This allows to have randomized resource records (i.e. each
answer contains only one IP, but the IP changes every request) for
A, AAAA records.

It will fix https://github.com/hashicorp/consul/issues/3355 and
https://github.com/hashicorp/consul/issues/3937

See https://github.com/hashicorp/consul/issues/3937#issuecomment-370610509
for details.

It basically add a new option called `a_record_limit` and will not
return more than a_record_limit when performing A, AAAA or ANY DNS
requests.

The existing `udp_answer_limit` option is still working but should
be considered as deprecated since it works only with DNS clients

Frank Schröder 874e350b2f config: add -config-format option (#3626)
* config: refactor ReadPath(s) methods without side-effects

Return the sources instead of modifying the state.

* config: clean data dir before every test

* config: add tests for config-file and config-dir

* config: add -config-format option

Starting with Consul 1.0 all config files must have a '.json' or '.hcl'
extension to make it unambigous how the data should be parsed. Some
automation tools generate temporary files by appending a random string
to the generated file which obfuscates the extension and prevents the
file type detection.

This patch adds a -config-format option which can be used to override
the auto-detection behavior by forcing all config files or all files
within a config directory independent of their extension to be
interpreted as of this format.

Fixes #3620

config: return error on extra command line arguments (#3397)
The `consul agent` command was ignoring extra command line arguments
which can lead to confusion when the user has for example forgotten to
add a dash in front of an argument or is not using an `=` when setting
boolean flags to `true`. `-bootstrap true` is not the same as
`-bootstrap=true`, for example.

Since all command line flags are known and we don't expect unparsed
arguments we can return an error. However, this may make it slightly
more difficult in the future if we ever wanted to have these kinds of
arguments.

Frank Schröder 94f58199b1 agent: add option to discard health output (#3562)
* agent: add option to discard health output

In high volatile environments consul will have checks with "noisy"
output which changes every time even though the status does not change.
Since the output is stored in the raft log every health check update
unblocks a blocking call on health checks since the raft index has
changed even though the status of the health checks may not have changed
at all. By discarding the output of the health checks the users can
choose a different tradeoff. Less visibility on why a check failed in
exchange for a reduced change rate on the raft log.

* agent: discard output also when adding a check

* agent: add test for discard check output

* agent: update docs

* go vet

* Adds discard_check_output to reloadable config table.

* Updates the change log.

Frank Schröder 759ef8a1d4 config: add generic method to translate between CamelCase and snake_case (#3557)
* doc: document discrepancy between id and CheckID

* doc: document enable_tag_override change

* config: add TranslateKeys helper

TranslateKeys makes it easier to map between different representations
of internal structures. It allows to recursively map alias keys to
canonical keys in structured maps.

* config: use TranslateKeys for config file

This also adds support for 'enabletagoverride' and removes
the need for a separate CheckID alias field.

* config: remove dead code

* agent: use TranslateKeys for FixupCheckType

* agent: translate enable_tag_override during service registration

* doc: add '.hcl' as valid extension

* config: map ScriptArgs to args

* config: add comment for TranslateKeys

James Phillips bb12368eac Makes RPC handling more robust when rolling servers. (#3561)
* Adds client-side retry for no leader errors.

This paves over the case where the client was connected to the leader
when it loses leadership.

* Adds a configurable server RPC drain time and a fail-fast path for RPCs.

When a server leaves it gets removed from the Raft configuration, so it will
never know who the new leader server ends up being. Without this we'd be
doomed to wait out the RPC hold timeout and then fail. This makes things fail
a little quicker while a sever is draining, and since we added a client retry
AND since the server doing this has already shut down and left the Serf LAN,
clients should retry against some other server.

* Makes the RPC hold timeout configurable.

* Reorders struct members.

* Sets the RPC hold timeout default for test servers.

* Bumps the leave drain time up to 5 seconds.

* Robustifies retries with a simpler client-side RPC hold.

* Reverts untended delete.

Frank Schröder 12216583a1 New config parser, HCL support, multiple bind addrs (#3480)
* new config parser for agent

This patch implements a new config parser for the consul agent which
makes the following changes to the previous implementation:

 * add HCL support
 * all configuration fragments in tests and for default config are
   expressed as HCL fragments
 * HCL fragments can be provided on the command line so that they
   can eventually replace the command line flags.
 * HCL/JSON fragments are parsed into a temporary Config structure
   which can be merged using reflection (all values are pointers).
   The existing merge logic of overwrite for values and append
   for slices has been preserved.
 * A single builder process generates a typed runtime configuration
   for the agent.

The new implementation is more strict and fails in the builder process
if no valid runtime configuration can be generated. Therefore,
additional validations in other parts of the code should be removed.

The builder also pre-computes all required network addresses so that no
address/port magic should be required where the configuration is used
and should therefore be removed.

* improve error messages

* fix directory permission test
