fixes #17097 Consul version of each nodes in UI nodes section

@jkirschner-hashicorp @huikang @team @Maintainers

Updated consul version in the request to register consul.
Added this as Node MetaData.
Fetching this new metadata in UI

Also made this backward compatible and tested.

Backward compatible in this context means - If consul binary with above
PR changes is deployed to one of node, and if UI is run from this node,
then the version of not only current (upgraded) node is displayed in UI
, but also of older nodes given that they are consul servers only.
For older (non-server or client) nodes the version is not added in
NodeMeta Data and hence the version will not be displayed for them.
If a old node is consul server, the version will be displayed. As the
endpoint - "v1/internal/ui/nodes?dc=dc1" was already returning version
in service meta. This is made use of in current UI changes.

Use agent token for service/check deregistration during anti-entropy (#16097)
Use only the agent token for deregistration during anti-entropy

The previous behavior had the agent attempt to use the "service" token
(i.e. from the `token` field in a service definition file), and if that
was not set then it would use the agent token.

The previous behavior was problematic because, if the service token had
been deleted, the deregistration request would fail. The agent would
retry the deregistration during each anti-entropy sync, and the
situation would never resolve.

The new behavior is to only/always use the agent token for service and
check deregistration during anti-entropy. This approach is:

* Simpler: No fallback logic to try different tokens
* Faster (slightly): No time spent attempting the service token
* Correct: The agent token is able to deregister services on that
  agent's node, because:
  * node:write permissions allow deregistration of services/checks on
    that node.
  * The agent token must have node:write permission, or else the agent
    is not be able to (de)register itself into the catalog

Max Bowsher 884a63431e Delete definition of metric `consul.acl.blocked.node.registration`
Although the metric is defined, there is no code which ever sets its
value - the code in question is genuinely asymmetric - there are 3 types
of object for which registration can be tracked, but only 2 for which
deregistration can be tracked.

Move ACLResolveResult into acl/resolver package (#13467)
Having this type live in the agent/consul package makes it difficult to
put anything that relies on token resolution (e.g. the new gRPC services)
in separate packages without introducing import cycles.

For example, if package foo imports agent/consul for the ACLResolveResult
type it means that agent/consul cannot import foo to register its service.

We've previously worked around this by wrapping the ACLResolver to
"downgrade" its return type to an acl.Authorizer - aside from the
added complexity, this also loses the resolved identity information.

In the future, we may want to move the whole ACLResolver into the
acl/resolver package. For now, putting the result type there at least,
fixes the immediate import cycle issues.

local: fixes a data race in anti-entropy sync (#12324)
The race detector noticed this initially in `TestAgentConfigWatcherSidecarProxy` but it is not restricted to just tests.

The two main changes here were:

- ensure that before we mutate the internal `agent/local` representation of a Service (for tags or VIPs) we clone those fields
- ensure that there's no function argument joint ownership between the caller of a function and the local state when calling `AddService`, `AddCheck`, and related using `copystructure` for now.

Jared Kirschner a9371f18e5 Clarify service and check error messages (use ID)
Error messages related to service and check operations previously included
the following substrings:
- service %q
- check %q

From this error message, it isn't clear that the expected field is the ID for
the entity, not the name. For example, if the user has a service named test,
the error message would read 'Unknown service "test"'. This is misleading -
a service with that *name* does exist, but not with that *ID*.

The substrings above have been modified to make it clear that ID is needed,
not name:
- service with ID %q
- check with ID %q

Daniel Nephin 76a365d410 local: default to the agent token instead of the user token
When de-registering in anti-entropy sync, when there is no service or
check token.

The agent token will fall back to the default (aka user) token if no agent
token is set, so the existing behaviour still works, but it will prefer
the agent token over the user token if both are set.

ref: https://www.consul.io/docs/agent/options#acl_tokens

The agent token seems more approrpiate in this case, since this is an
"internal operation", not something initiated by the user.

These types are used as values (not pointers) in other structs. Using a pointer receiver causes

Also remove some unused methods.
