xds: don't attempt to load-balance sessions for local proxies (#15789)
Previously, we'd begin a session with the xDS concurrency limiter
regardless of whether the proxy was registered in the catalog or in
the server's local agent state.

This caused problems for users who run `consul connect envoy` directly
against a server rather than a client agent, as the server's locally
registered proxies wouldn't be included in the limiter's capacity.

Now, the `ConfigSource` is responsible for beginning the session and we
only do so for services in the catalog.

Fixes: https://github.com/hashicorp/consul/issues/15753

Prevent serving TLS via ports.grpc (#15339)
Prevent serving TLS via ports.grpc

We remove the ability to run the ports.grpc in TLS mode to avoid
confusion and to simplify configuration. This breaking change
ensures that any user currently using ports.grpc in an encrypted
mode will receive an error message indicating that ports.grpc_tls
must be explicitly used.

The suggested action for these users is to simply swap their ports.grpc
to ports.grpc_tls in the configuration file. If both ports are defined,
or if the user has not configured TLS for grpc, then the error message
will not be printed.

Refactor client RPC timeouts (#14965)
Fix an issue where rpc_hold_timeout was being used as the timeout for non-blocking queries. Users should be able to tune read timeouts without fiddling with rpc_hold_timeout. A new configuration `rpc_read_timeout` is created.

Refactor some implementation from the original PR 11500 to remove the misleading linkage between RPCInfo's timeout (used to retry in case of certain modes of failures) and the client RPC timeouts.

proxycfg: rate-limit delivery of config snapshots (#14960)
Adds a user-configurable rate limiter to proxycfg snapshot delivery,
with a default limit of 250 updates per second.

This addresses a problem observed in our load testing of Consul
Dataplane where updating a "global" resource such as a wildcard
intention or the proxy-defaults config entry could starve the Raft or
Memberlist goroutines of CPU time, causing general cluster instability.

Service http checks data source for agentless proxies (#14924)
Adds another datasource for proxycfg.HTTPChecks, for use on server agents. Typically these checks are performed by local client agents and there is no equivalent of this in agentless (where servers configure consul-dataplane proxies).
Hence, the data source is mostly a no-op on servers but in the case where the service is present within the local state, it delegates to the cache data source.

freddygv f4cc4577ca Fix alias check leak
Preivously when alias check was removed it would not be stopped nor
cleaned up from the associated aliasChecks map.

This means that any time an alias check was deregistered we would
leak a goroutine for CheckAlias.run() because the stopCh would never
be closed.

This issue mostly affects service mesh deployments on platforms where
the client agent is mostly static but proxy services come and go
regularly, since by default sidecars are registered with an alias check.

xDS Load Balancing (#14397)
Prior to #13244, connect proxies and gateways could only be configured by an
xDS session served by the local client agent.

In an upcoming release, it will be possible to deploy a Consul service mesh
without client agents. In this model, xDS sessions will be handled by the
servers themselves, which necessitates load-balancing to prevent a single
server from receiving a disproportionate amount of load and becoming
overwhelmed.

This introduces a simple form of load-balancing where Consul will attempt to
achieve an even spread of load (xDS sessions) between all healthy servers.
It does so by implementing a concurrent session limiter (limiter.SessionLimiter)
and adjusting the limit according to autopilot state and proxy service
registrations in the catalog.

If a server is already over capacity (i.e. the session limit is lowered),
Consul will begin draining sessions to rebalance the load. This will result
in the client receiving a `RESOURCE_EXHAUSTED` status code. It is the client's
responsibility to observe this response and reconnect to a different server.

Users of the gRPC client connection brokered by the
consul-server-connection-manager library will get this for free.

The rate at which Consul will drain sessions to rebalance load is scaled
dynamically based on the number of proxies in the catalog.

sources for which there is to be no server-local equivalent.

Derek Menteer 1255a8a20d Add separate grpc_tls port.
To ease the transition for users, the original gRPC
port can still operate in a deprecated mode as either
plain-text or TLS mode. This behavior should be removed
in a future release whenever we no longer support this.

The resulting behavior from this commit is:
  `ports.grpc > 0 && ports.grpc_tls > 0` spawns both plain-text and tls ports.
  `ports.grpc > 0 && grpc.tls == undefined` spawns a single plain-text port.
  `ports.grpc > 0 && grpc.tls != undefined` spawns a single tls port (backwards compat mode).

grpc: rename public/private directories to external/internal (#13721)
Previously, public referred to gRPC services that are both exposed on
the dedicated gRPC port and have their definitions in the proto-public
directory (so were considered usable by 3rd parties). Whereas private
referred to services on the multiplexed server port that are only usable
by agents and other servers.

Now, we're splitting these definitions, such that external/internal
refers to the port and public/private refers to whether they can be used
by 3rd parties.

This is necessary because the peering replication API needs to be
exposed on the dedicated port, but is not (yet) suitable for use by 3rd
parties.

server: broadcast the public grpc port using lan serf and update the consul service in the catalog with the same data (#13687)
Currently servers exchange information about their WAN serf port
and RPC port with serf tags, so that they all learn of each other's
addressing information. We intend to make larger use of the new
public-facing gRPC port exposed on all of the servers, so this PR
addresses that by passing around the gRPC port via serf tags and
then ensuring the generated consul service in the catalog has
metadata about that new port as well for ease of non-serf-based lookup.

Daniel Upton 45886848b4 proxycfg: server-local intention upstreams data source
This is the OSS portion of enterprise PR 2157.

It builds on the local blocking query work in #13438 to implement the
proxycfg.IntentionUpstreams interface using server-local data.

Also moves the ACL filtering logic from agent/consul into the acl/filter
package so that it can be reused here.

Daniel Upton 37ccbd2826 proxycfg: server-local intentions data source
This is the OSS portion of enterprise PR 2141.

This commit provides a server-local implementation of the `proxycfg.Intentions`
interface that sources data from streaming events.

It adds events for the `service-intentions` config entry type, and then consumes
event streams (via materialized views) for the service's explicit intentions and
any applicable wildcard intentions, merging them into a single list of intentions.

An alternative approach I considered was to consume _all_ intention events (via
`SubjectWildcard`) and filter out the irrelevant ones. This would admittedly
remove some complexity in the `agent/proxycfg-glue` package but at the expense
of considerable overhead from waking potentially many thousands of connect
proxies every time any intention is updated.

Daniel Upton 653b8c4f9d proxycfg: server-local config entry data sources
This is the OSS portion of enterprise PR 2056.

This commit provides server-local implementations of the proxycfg.ConfigEntry
and proxycfg.ConfigEntryList interfaces, that source data from streaming events.

It makes use of the LocalMaterializer type introduced for peering replication,
adding the necessary support for authorization.

It also adds support for "wildcard" subscriptions (within a topic) to the event
publisher, as this is needed to fetch service-resolvers for all services when
configuring mesh gateways.

Currently, events will be emitted for just the ingress-gateway, service-resolver,
and mesh config entry types, as these are the only entries required by proxycfg
— the events will be emitted on topics named IngressGateway, ServiceResolver,
and MeshConfig topics respectively.

Though these events will only be consumed "locally" for now, they can also be
consumed via the gRPC endpoint (confirmed using grpcurl) so using them from
client agents should be a case of swapping the LocalMaterializer for an
RPCMaterializer.

Add internal endpoint to fetch peered upstream candidates from VirtualIP table (#13642)
For initial cluster peering TProxy support we consider all imported services of a partition to be potential upstreams.

We leverage the VirtualIP table because it stores plain service names (e.g. "api", not "api-sidecar-proxy").

Move ACLResolveResult into acl/resolver package (#13467)
Having this type live in the agent/consul package makes it difficult to
put anything that relies on token resolution (e.g. the new gRPC services)
in separate packages without introducing import cycles.

For example, if package foo imports agent/consul for the ACLResolveResult
type it means that agent/consul cannot import foo to register its service.

We've previously worked around this by wrapping the ACLResolver to
"downgrade" its return type to an acl.Authorizer - aside from the
added complexity, this also loses the resolved identity information.

In the future, we may want to move the whole ACLResolver into the
acl/resolver package. For now, putting the result type there at least,
fixes the immediate import cycle issues.

xds: remove HTTPCheckFetcher dependency (#13366)
This is the OSS portion of enterprise PR 1994

Rather than directly interrogating the agent-local state for HTTP
checks using the `HTTPCheckFetcher` interface, we now rely on the
config snapshot containing the checks.

This reduces the number of changes required to support server xDS
sessions.

It's not clear why the fetching approach was introduced in
931d167ebb.

Freddy a09c776645 Update public listener with SPIFFE Validator
Envoy's SPIFFE certificate validation extension allows for us to
validate against different root certificates depending on the trust
domain of the dialing proxy.

If there are any trust bundles from peers in the config snapshot then we
use the SPIFFE validator as the validation context, rather than the
usual TrustedCA.

The injected validation config includes the local root certificates as
well.

There are a handful of changes in this commit:

* The endpoint needs to track the index because the cache watches use
  it.
* Extracted bulk of the endpoint's logic to a state store function
  so that index tracking could be tested more easily.
* Removed check for service existence, deferring that sort of work to ACL authz
* Added the cache type

Configure upstream TLS context with peer root certs (#13321)
For mTLS to work between two proxies in peered clusters with different root CAs,
proxies need to configure their outbound listener to use different root certificates
for validation.

Up until peering was introduced proxies would only ever use one set of root certificates
to validate all mesh traffic, both inbound and outbound. Now an upstream proxy
may have a leaf certificate signed by a CA that's different from the dialing proxy's.

This PR makes changes to proxycfg and xds so that the upstream TLS validation
uses different root certificates depending on which cluster is being dialed.

Enable servers to configure arbitrary proxies from the catalog (#13244)
OSS port of enterprise PR 1822

Includes the necessary changes to the `proxycfg` and `xds` packages to enable
Consul servers to configure arbitrary proxies using catalog data.

Broadly, `proxycfg.Manager` now has public methods for registering,
deregistering, and listing registered proxies — the existing local agent
state-sync behavior has been moved into a separate component that makes use of
these methods.

When an xDS session is started for a proxy service in the catalog, a goroutine
will be spawned to watch the service in the server's state store and
re-register it with the `proxycfg.Manager` whenever it is updated (and clean
it up when the client goes away).

proxycfg: remove dependency on `cache.UpdateEvent` (#13144)
OSS portion of enterprise PR 1857.

This removes (most) references to the `cache.UpdateEvent` type in the
`proxycfg` package.

As we're going to be direct usage of the agent cache with interfaces that
can be satisfied by alternative server-local datasources, it doesn't make
sense to depend on this type everywhere anymore (particularly on the
`state.ch` channel).

We also plan to extract `proxycfg` out of Consul into a shared library in
the future, which would require removing this dependency.

Aside from a fairly rote find-and-replace, the main change is that the
`cache.Cache` and `health.Client` types now accept a callback function
parameter, rather than a `chan<- cache.UpdateEvents`. This allows us to
do the type conversion without running another goroutine.

Mark Anderson 346b68a441 Fix up enterprise version tag.
Changes to how the version string was handled created small regression with the release of consul 1.12.0 enterprise.

Many tools use the Config:Version field reported by the agent/self resource to determine whether Consul is an enterprise or OSS instance, expect something like 1.12.0+ent for enterprise and simply 1.12.0 for OSS. This was accidentally broken during the runup to 1.12.x

This work fixes the value returned by both the self endpoint in ["Config"]["Version"] and the metrics consul.version field.
