When a queue subscriber was updated multiple times over a leafnode
connection we added in more shadow subscriptions which could become
zombies when the connection went away.
In a case where a leafnode server had multiple queue subscribers on the
same queue group, the hub server would add in multiple shadow subs.
These subs would not be properly cleaned up and could lead to stale
connections being associated with them.

These tests are to help verify that routes aren't leaking when they go
down for write deadlines or auth failures.

If we're on a branch other than main or dev, then when building
"nightly", build it with the name of the branch instead. Overrideable
via an env var.
It's a bit ugly because of limitations of goreleaser templating, we
can't haul the expression out to be defined once, but it works.
Can build a custom Docker image with:
goreleaser release --snapshot -p 2 -f .goreleaser-nightly.yml --clean

When creating a consumer on a stream with a very large number of msg
blks, calculating numPending could be slow.
This aims to optimize a bit, more work to be done on streams with a very
large (> 200k) number of msg blks.

This fixes#4252 by ensuring that `tls_available`, `tls_required`,
`host` and `port` are populated based on the WebSocket listener rather
than standard listeners.

This unit test is modelled around issue #4247 and proves that the
`MaxMsgs` and `MaxMsgsPer` limits are correctly enforced together with
`DiscardNew` and `DiscardNewPer`.

This test has multiple leafnode connections to different accounts and to
a shared account to make sure behavior is correct.

When creating replicated mirrors where the source stream had a very
large starting sequence number, the server would use excessive CPU and
Memory.
This is due to the mirroring functionality trying to skip messages when
it detects a gap. In a replicated stream this puts excessive stress on
the raft system.
This step is not needed at all if the mirror stream has no messages, we
can simply jump ahead.
