Update HCP bootstrapping to support existing clusters (#16916)
* Persist HCP management token from server config

We want to move away from injecting an initial management token into
Consul clusters linked to HCP. The reasoning is that by using a separate
class of token we can have more flexibility in terms of allowing HCP's
token to co-exist with the user's management token.

Down the line we can also more easily adjust the permissions attached to
HCP's token to limit it's scope.

With these changes, the cloud management token is like the initial
management token in that iit has the same global management policy and
if it is created it effectively bootstraps the ACL system.

* Update SDK and mock HCP server

The HCP management token will now be sent in a special field rather than
as Consul's "initial management" token configuration.

This commit also updates the mock HCP server to more accurately reflect
the behavior of the CCM backend.

* Refactor HCP bootstrapping logic and add tests

We want to allow users to link Consul clusters that already exist to
HCP. Existing clusters need care when bootstrapped by HCP, since we do
not want to do things like change ACL/TLS settings for a running
cluster.

Additional changes:

* Deconstruct MaybeBootstrap so that it can be tested. The HCP Go SDK
  requires HTTPS to fetch a token from the Auth URL, even if the backend
  server is mocked. By pulling the hcp.Client creation out we can modify
  its TLS configuration in tests while keeping the secure behavior in
  production code.

* Add light validation for data received/loaded.

* Sanitize initial_management token from received config, since HCP will
  only ever use the CloudConfig.MangementToken.

* Add changelog entry

troubleshoot: make output have tables and colors (#16235)
Adds tables and colors using libraries used in consul-k8s. It doesn't add the full `terminal` UI package that consul-k8s uses since there is an existing UI in Consul that I didn't want to affect too much. So instead this adds to the existing UI.

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).

Support per-listener TLS configuration ⚙️ (#12504)
Introduces the capability to configure TLS differently for Consul's
listeners/ports (i.e. HTTPS, gRPC, and the internal multiplexed RPC
port) which is useful in scenarios where you may want the HTTPS or
gRPC interfaces to present a certificate signed by a well-known/public
CA, rather than the certificate used for internal communication which
must have a SAN in the form `server.<dc>.consul`.

Daniel Nephin cec8bc88a9 cmd: remove unnecessary GatedUi
The intent of this struct was to prevent non-json output to stdout. With
the previous cleanup, this can now be done by simply changing the stdout
stream to io.Discard.

This is just one example of why passing around io.Writers for the
streams is better than the UI interface.

Daniel Nephin 2261a469e3 cmd: move agent running message to logs
Previously this line was mixed up with logging, which made the output

directly to stdout.

This has the advantage that the message will be visible when json logs
are enabled.

and an arg.

Daniel Nephin 1dcafa51a4 config: make config.TestLoad_FullConfig use config.Load
This commit makes a number of changes that should make
TestLoad_FullConfig easier to work with, and make the test more like
real world scenarios.

* use separate files in testdata/ dir to store the config source.
  Separate files are much easier to edit because editors can syntax
  highlight json/hcl, and it makes strings easier to find. Previously
  trying to find strings would match strings used in other tests.
* use the exported config.Load interface instead of internal NewBuilder
  and BuildAndValidate.
* remove the tail config overrides, which are only necessary with
  nonZero works.

Daniel Nephin 97a577502d config: improve the interface of Load
This commit reduces the interface to Load() a bit, in preparation for
unexporting NewBuilder and having everything call Load.

The three arguments are reduced to a single argument by moving the other
two into the options struct.

The three return values are reduced to two by moving the RuntimeConfig
and Warnings into a LoadResult struct.

Daniel Nephin b9e60c0775 testing: skip slow tests with -short
Add a skip condition to all tests slower than 100ms.

This change was made using `gotestsum tool slowest` with data from the
last 3 CI runs of master.
See https://github.com/gotestyourself/gotestsum#finding-and-skipping-slow-tests

With this change:

```
$ time go test -count=1 -short ./agent
ok      github.com/hashicorp/consul/agent       0.743s

real    0m4.791s

There are still a number of dependencies created in Start() which can
be addressed in a follow up.

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.

Daniel Nephin 77101eee82 config: rename Flags to BuilderOpts
Flags is an overloaded term in this context. It generally is used to
refer to command line flags. This struct, however, is a data object
used as input to the construction.

It happens to be partially populated by command line flags, but
otherwise has very little to do with them.

Renaming this struct should make the actual responsibility of this struct
more obvious, and remove the possibility that it is confused with
command line flags.

This change is in preparation for adding additional fields to
BuilderOpts.

Daniel Nephin 85e0338136 config: remove Args field from Flags
This field was populated for one reason, to test that it was empty.
Of all the callers, only a single one used this functionality. The rest
constructed a `Flags{}` struct which did not set Args.

I think this shows that the logic was in the wrong place. Only the agent
command needs to care about validating the args.

This commit removes the field, and moves the logic to the one caller
that cares.

Also fix some comments.
