Commit Message

[IMPROVED] Speed up a mirror or source consumer's resync across leafnode connections. (#6981)

When a consumer for a source or a mirror is failing to be created, we
backoff creation attempts.
If the failures were due to a downed leafnode, meaning the mirror or
source is across a leafnode connection, the resync could take more time
then desired after the leafnode reconnects.

This improves resync time by hooking into the leafnode's reconnect logic
(either via connect or async info).
Once we detect the reconnect, we search for streams that are leaders and
are mirrors or sources, and do not have an active sync consumer.

If we detect this we will reset the consumer backoff and retry with just
a small jitter backoff.
