An example was a "consumer info" request with a consumer name that
had tokens, which is illegal. This results in the request being
dropped in apiDispatch() because there was no interest.
The server will now return a "bad request" error in such case.

Some warnings, especially when dealing with JS limits that were
printed on a per-message basis, are now limited to ~1 per second
if the content of the warning is already found in a map.
This is also for "client" warnings, but the client porting of the
warning is not taken into account so that helps with reducing logging
for similar content, but coming from different clients.

Also fixed some flappers and removed use of `s.js.` since we have
already captured `js` in Jsz monitoring.

We were also not copying over local state that has been added over the years to track different types of clients.
We also needed to make sure to reuse the account's internal client and the subscription id (acc.isid).

This was introduced in v2.6.6. In order to solve a config reload
issue, we used tls.Config.GetConfigForClient which allowed the
TLS configuration to be "refreshed" with the latest. However, in
this case, the tls.Config.ClientAuth was not reset to tls.NoClientCert
which we need for monitoring port.

Kubernetes probes don't use nor log the reponse body of health
endpoints. This means that for some reason a nats node running in
Kubernetes becomes on a Not Ready state we won't have a way to know why
other than to manually access the cluster and call the /healthz endpoint
manually and see the error.
This change adds an error log so we can observe what is going wrong with
a nats node that is not ready.

Also fixed a bug that could cause memory based replicated consumers to no longer work after snapshots and server restarts.
The snapshot logic would allow non-state changing updates to continously grow the raft logs. We also were too conservative on when we snapshotted and why.
Also added in ability to have FileStore.Compact() reclaim space from the block file from the head of last changed block.

Also, remove some condition in gateway.go on how we were checking
if a subject was a serviec reply, which was causing a test to flap.
Finally, used AckSync() in a rest (instead of m.Respond(nil)) to
prevent it from flapping.
