Daniel Nephin 282fbdfa75 api: rename HTTPServer to HTTPHandlers
Resolves a TODO about naming. This type is a set of handlers for an http.Server, it is not
itself a Server. It provides http.Handler functions.

Daniel Nephin 330be5b740 agent/token: Move token persistence out of agent
And into token.Store. This change isolates any awareness of token
persistence in a single place.

It is a small step in allowing Agent.New to accept its dependencies.

Daniel Nephin 1912c5ad89 testing: wait until monitor has started before shutdown
This commit fixes a test that I saw flake locally while running tests. The test output from the monitor
started immediately after the line the test was looking for.

To fix the problem a channel is closed when the goroutine starts. Shutdown is not called until this channel
is closed, which seems to greatly reduce the chance of a flake.

Disable background cache refresh for Connect Leaf Certs
The rationale behind removing them is that all of our own code (xDS, builtin connect proxy) use the cache notification mechanism. This ensures that the blocking fetch behind the scenes is always executing. Therefore the only way you might go to get a certificate and have to wait is when 1) the request has never been made for that cert before or 2) you are using the v1/agent/connect/ca/leaf API for retrieving the cert yourself.

In the first case, the refresh change doesn’t alter the behavior. In the second case, it can be mitigated by using blocking queries with that API which just like normal cache notification mechanism will cause the blocking fetch to be initiated and to get leaf certs as soon as needed.

If you are not using blocking queries, or Envoy/xDS, or the builtin connect proxy but are retrieving the certs yourself then the HTTP endpoint might take a little longer to respond.

This also renames the RefreshTimeout field on the register options to QueryTimeout to more accurately reflect that it is used for any type that supports blocking queries.

Daniel Nephin a5e45defb1 agent/http: un-embed the HTTPServer
The embedded HTTPServer struct is not used by the large HTTPServer
struct. It is used by tests and the agent. This change is a small first
step in the process of removing that field.

The eventual goal is to reduce the scope of HTTPServer making it easier
to test, and split into separate packages.

Implement Client Agent Auto Config
There are a couple of things in here.

First, just like auto encrypt, any Cluster.AutoConfig RPC will implicitly use the less secure RPC mechanism.

This drastically modifies how the Consul Agent starts up and moves most of the responsibilities (other than signal handling) from the cli command and into the Agent.

agent: add ACL enforcement to the v1/agent/health/service/* endpoints
This adds acl enforcement to the two endpoints that were missing it.

Note that in the case of getting a services health by its id, we still
must first lookup the service so we still "leak" information about a
service with that ID existing. There isn't really a way around it though
as ACLs are meant to check service names.

Ensure we close the Sentinel Evaluator so as not to leak go routines

Fix a bunch of test logging so that various warnings when starting a test agent go to the ltest logger and not straight to stdout.

Various canned ent meta types always return a valid pointer (no more nils). This allows us to blindly deref + assign in various places.

Update ACL index tracking to ensure oss -> ent upgrades will work as expected.

Update ent meta parsing to include function to disallow wildcarding.

connect: connect CA Roots in secondary datacenters should use a SigningKeyID derived from their local intermediate (#6513)
This fixes an issue where leaf certificates issued in secondary
datacenters would be reissued very frequently (every ~20 seconds)
because the logic meant to detect root rotation was errantly triggering
because a hash of the ultimate root (in the primary) was being compared
against a hash of the local intermediate root (in the secondary) and
always failing.

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.

  (not exhaustive yet).

* Switch to ioutil.ReadFile for all types of agent persistence.

* Support for maximum size for Output of checks

This PR allows users to limit the size of output produced by checks at the agent 
and check level.

When set at the agent level, it will limit the output for all checks monitored
by the agent.

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.
