Under some scenarios a client may hit the slow consumer
write deadline during the connecting stage, meaning that
it is possible to consider unhealthy clients could not
finish the TLS handshake as slow consumers.
With this change, we only consider as slow consumers
clients that did connect to the cluster without issues.

Converted to authorization error events on different subject.
Add cluster name if gateways are configured and pass in INFO to clients.

Otherwise, this may be sent to servers in the cluster and to other
gateways which may result in attempt to connect to self which
in case of TLS would produce error.

Do the swapping to outbound connection only on send.
It means that those subs are stored in the inbound connection and
those are the only type of subs stored there. So on connection close
it is easy to clean them up.
Also instead of having processMsgResults have to return this sub,
simply check the size of r.psubs and if 1, the type of client
associated with it. If gateway, we know we have to do the direct
send.

This adds a RemoteAddress() method to the ClientAuthentication
interface which would facilitate CustomClientAuthentication
mechanisms considering the remote IP address of the client in
their decisions to allow clients or not

This is not complete solution and is a bit hacky but is a start
to be able to have service import work at least in some basic
cases.
Also fixed a bug where replySub would not be removed from
connection's list of subs after delivery.

Changed account lookup and validation failures to be more understandable by users.
Changed limits to be -1 for unlimited to match jwt pkg.
The limits changed exposed problems with options holding real objects causing issues with reload tests under race mode.
Longer term this code should be reworked such that options only hold config data, not real structs, etc.

When a TLS timeout occurs, it was possible that code trying to
send data would get a timeout error and report it as a Slow Consumer
with the write deadline exceeded error.
Checking that if the connection is TLS and handshake not complete,
it is likely a TLS timeout error instead.

Although Gateways reload is not supported at the moment, I had
to add the trap in the switch statement because it would find
a difference. The reason is the TLSConfig object that is likely
to not pass the reflect.DeepEqual test. So for now, I exclude this
from the deep equal test and fail the reload only if the user
has explicitly changed the configuration.

Removed the code getting matching subscriptions and trying
to exclude non internal interest since as soon as there is
routing and/or gateway, it is likely that server would end-up
generating the payload and sending. May need to revisit.
