agent: enable reloading of tls config (#5419)
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.

Aestek ce447e0e16 Fix race condition in DNS when using cache (#5398)
* 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

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.

Jack Pearkes 197d62c6ca New command: consul debug (#4754)
* agent/debug: add package for debugging, host info

* api: add v1/agent/host endpoint

* agent: add v1/agent/host endpoint

* command/debug: implementation of static capture

* command/debug: tests and only configured targets

* agent/debug: add basic test for host metrics

* command/debug: add methods for dynamic data capture

* api: add debug/pprof endpoints

* command/debug: add pprof

* command/debug: timing, wg, logs to disk

* vendor: add gopsutil/disk

* command/debug: add a usage section

* website: add docs for consul debug

* agent/host: require operator:read

* api/host: improve docs and no retry timing

* command/debug: fail on extra arguments

* command/debug: fixup file permissions to 0644

* command/debug: remove server flags

* command/debug: improve clarity of usage section

* api/debug: add Trace for profiling, fix profile

* command/debug: capture profile and trace at the same time

* command/debug: add index document

* command/debug: use "clusters" in place of members

* command/debug: remove address in output

* command/debug: improve comment on metrics sleep

* command/debug: clarify usage

* 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()

Pierre Souchay 42f250fa53 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
