b344519176 [FIXED] MQTT: Same session ID in different domains were considered duplicates 
There is a mechanism to detect if a connection somewhere in the
cluster is using the session ID of an existing one, and if so,
close one as a duplicate.
However, when different domains are used, they should not be considered
duplicates.

66b1b51182 [FIXED] MQTT: Errors deleting consumers will now prevent deletion of session 
When there was a failure to delete a QoS1 consumer, the session
would still be deleted, which would cause orphaned consumers.

In case of error, the session record will not be deleted, which means
that it is still possible to restart the session and then close
it (with the clean flag).

Relates to #3116

4bf81420e2 [FIXED] Fast routed JetStream API requests were dropped 
If a JS API request is received from a non client connection, it
was processed in its own go routine. To reduce the number of
such go routine, we were limiting the number of outstanding routines
to 4096. However, in some situations, it was possible to issue
many requests at the same time that would then cause those requests
to be dropped.

(an example was an MQTT benchmark tool that would create 5000
sessions, each with one QoS1 R1 consumer (with the use of consumer_replicas=1).
On abrupt exit of the tool, the consumers and their sessions needed
to be deleted. Since would cause fast incoming delete consumer requests
which would cause the original code to drop some of them)

5d3b1743e3 [ADDED] MQTT: Stream/Consumer replica count override 
Ability to override the stream and consumers replica count, which is by default
determined based on the cluster size.

```
mqtt {
  port: 1883
  stream_replicas: 5
  consumer_replicas: 1
}
```

The above would allow *new* MQTT streams to be created with a replicas
factor of 5 (it will be an error if the cluster does not have that
many nodes, and error will occur at runtime when the first client
on a given account connects), and new consumers would be R=1.

The MQTT existing streams/consumers for an account are not modified.

The stream_replicas can also obviously be reduced to 1 for a cluster
of 3 nodes if one desire to have those streams as R=1.

A value of 0 or negative is considered letting the server pick
the value (from 1 to 3 depending on standalone/cluster size).

There is another property that allows the consumers to be created
with memory storage instead of file:
```
mqtt {
  ..
  consumer_memory_storage: true
}
```

Those new settings are global and apply to new streams/consumers
only.
