know we have external interest.

If we know we are in stand alone mode we do not need to run the updates
for JetStream account resources updates.

Resolves#4227 (Partial)
When messages were very small and the key space was very large the
performance of last message gets in the store layer (both file and
memory) would degrade.
If the subject is literal we can optimize and avoid sequence scans that
are needed when multiple subject states need to be considered.

### Changes proposed in this pull request:
- Refactors BenchmarkJetStream(Consume|Publish) and BenchmarkJetStreamKV
benchmarks to connect to stream leader for benchmark cases where cluster
size is greater than 1.
- BenchmarkJetStreamKV now only targets a single bucket (B=1).

When a server would send an asynchronous INFO to a remote server it
would incorrectly contain compression information that could cause
issues with one side thinking that the connection should be compressed
while the other side was not.
It also caused the authentication timer to be incorrectly set which
would cause a disconnect.

Fix for properly distributed queue requests over multiple leafnode
connections.
When a leafnode server joins two accounts in a supercluster, we want to
make sure that each connection properly takes into account the weighted
number of subscribers in each account.

It doesn't really appear as though, for what these tests are trying to
prove, that an excessively large number of messages is required. Instead
let's drop the count a little in the hope that they run a bit faster.

Bail early if new consumer, meaning stream sequence floor is 0.
Decide which linear space to scan.
Do no work if no pending and we just need to adjust which we do at the
end.
Also realized some tests were named wrong and were not being run, or
were in wrong file.

### Changes proposed in this pull request:
Adds a check that the stream name of a stream source is valid and
associated new error if it isn't.
Currently `UpdateKnownPeers` doesn't send a peer state when a single
peer add operation is taking place, but it seems like this can
potentially race when there are lots of changes to the replica count
happening in rapid succession. Sending the peer state in all cases seems
to fix this issue and, so far in my testing, fixes the failground stream
update replicas test.

When consumers were R1 and the same name was reused, server restarts
could try to cleanup old ones and effect the new ones. These changes
allow consumer name reuse more effectively during server restarts.
