This PR introduces reloading tls configuration. Consul will now be able to reload the TLS configuration which previously required a restart. It is not yet possible to turn TLS ON or OFF with these changes. Only when TLS is already turned on, the configuration can be reloaded. Most importantly the certificates and CAs.
* Fix race condition in DNS when using cache
The healty node filtering was modifying the result from the cache, which
caused a crash when multiple queries were made to the same service
simultaneously.
We now copy the node slice before filtering to ensure we do not modify
the data stored in the cache.
* Fix wording in dns cache config doc
s/dns_max_age/cache_max_age/
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.
Adds two new configuration parameters "dns_config.use_cache" and
"dns_config.cache_max_age" controlling how DNS requests use the agent
cache when querying servers.

* agent: always register pprof handlers and protect
This will allow us to avoid a restart of a target agent
for profiling by always registering the pprof handlers.
Given this is a potentially sensitive path, it is protected
with an operator:read ACL and enable debug being
set to true on the target agent. enable_debug still requires
a restart.
If ACLs are disabled, enable_debug is sufficient.
* command/debug: use trace.out instead of .prof
More in line with golang docs.
* agent: fix comment wording
* agent: wrap table driven tests in t.run()
* Add -enable-local-script-checks options
These options allow for a finer control over when script checks are enabled by
giving the option to only allow them when they are declared from the local
file system.
* Add documentation for the new option
* Nitpick doc wording
* Initial draft of Sidecar Service and Managed Proxy deprecation docs
* Service definition deprecation notices and sidecar service
* gRPC and sidecar service config options; Deprecate managed proxy options
* Envoy Docs: Basic envoy command; envoy getting started/intro
* Remove change that snuck in
* Envoy custom config example

* Added log-file flag to capture Consul logs in a user specified file
* Refactored code.
* Refactored code. Added flags to rotate logs based on bytes and duration

* Added test for logfile and updated the default log destination for docs
* Log name now uses UnixNano
* TestLogFile is now uses t.Parallel()
* Removed unnecessary int64Val function
* Updated docs to reflect default log name for log-file
* No longer writes to data-dir and adds .log if the filename has no extension
* updates docs for agent options
trying to add a little more clarity to suggestion that folks should use
port 8302 for both LAN and WAN comms
* website: clarify language for serf wan port behavior
* Added explainations on how having a working configuration for Prometheus
Since Prometheus escapes by default query parameters, this paragraph explains
how having `format=prometheus` to be taken into account by prometheus.
* Rephrase Prometheus notes in documentation as requested by @pearkes
The floating paragraph seems to need additional indentation to work correctly on the markdown parser middle man uses - GitHub got it right before in the preview but the website broke dumping the new config option inline.
