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

proxycfg: ensure that an irrecoverable error in proxycfg closes the xds session and triggers a replacement proxycfg watcher (#16497)
Receiving an "acl not found" error from an RPC in the agent cache and the
streaming/event components will cause any request loops to cease under the
assumption that they will never work again if the token was destroyed. This
prevents log spam (#14144, #9738).

Unfortunately due to things like:

- authz requests going to stale servers that may not have witnessed the token
  creation yet

- authz requests in a secondary datacenter happening before the tokens get
  replicated to that datacenter

- authz requests from a primary TO a secondary datacenter happening before the
  tokens get replicated to that datacenter

The caller will get an "acl not found" *before* the token exists, rather than
just after. The machinery added above in the linked PRs will kick in and
prevent the request loop from looping around again once the tokens actually
exist.

For `consul-dataplane` usages, where xDS is served by the Consul servers
rather than the clients ultimately this is not a problem because in that
scenario the `agent/proxycfg` machinery is on-demand and launched by a new xDS
stream needing data for a specific service in the catalog. If the watching
goroutines are terminated it ripples down and terminates the xDS stream, which
CDP will eventually re-establish and restart everything.

For Consul client usages, the `agent/proxycfg` machinery is ahead-of-time
launched at service registration time (called "local" in some of the proxycfg
machinery) so when the xDS stream comes in the data is already ready to go. If
the watching goroutines terminate it should terminate the xDS stream, but
there's no mechanism to re-spawn the watching goroutines. If the xDS stream
reconnects it will see no `ConfigSnapshot` and will not get one again until
the client agent is restarted, or the service is re-registered with something
changed in it.

This PR fixes a few things in the machinery:

- there was an inadvertent deadlock in fetching snapshot from the proxycfg
  machinery by xDS, such that when the watching goroutine terminated the
  snapshots would never be fetched. This caused some of the xDS machinery to
  get indefinitely paused and not finish the teardown properly.

- Every 30s we now attempt to re-insert all locally registered services into
  the proxycfg machinery.

- When services are re-inserted into the proxycfg machinery we special case
  "dead" ones such that we unilaterally replace them rather that doing that
  conditionally.

cache: refactor agent cache fetching to prevent unnecessary fetches on error (#14956)
This continues the work done in #14908 where a crude solution to prevent a
goroutine leak was implemented. The former code would launch a perpetual
goroutine family every iteration (+1 +1) and the fixed code simply caused a
new goroutine family to first cancel the prior one to prevent the
leak (-1 +1 == 0).

This PR refactors this code completely to:

- make it more understandable
- remove the recursion-via-goroutine strangeness
- prevent unnecessary RPC fetches when the prior one has errored.

The core issue arose from a conflation of the entry.Fetching field to mean:

- there is an RPC (blocking query) in flight right now
- there is a goroutine running to manage the RPC fetch retry loop

The problem is that the goroutine-leak-avoidance check would treat
Fetching like (2), but within the body of a goroutine it would flip that
boolean back to false before the retry sleep. This would cause a new
chain of goroutines to launch which #14908 would correct crudely.

The refactored code uses a plain for-loop and changes the semantics
to track state for "is there a goroutine associated with this cache entry"
instead of the former.

We use a uint64 unique identity per goroutine instead of a boolean so
that any orphaned goroutines can tell when they've been replaced when
the expiry loop deletes a cache entry while the goroutine is still running
and is later replaced.

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.

freddygv 5fbb26525b Add awareness of server mode to TLS configurator
Preivously the TLS configurator would default to presenting auto TLS
certificates as client certificates.

Server agents should not have this behavior and should instead present
the manually configured certs. The autoTLS certs for servers are
exclusively used for peering and should not be used as the default for
outbound communication.

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).

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.

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`.
