Commit Message

[IMPROVED] LoadNextMsg for wildcard consumers with millions of subjects (#5710)

When LoadNextMsg misses, make sure to consult psim but conservatively.

We had a use case with millions of subjects and the last sequence
checked being in the next to the last block. The consumer had a wildcard
that matched lots of entries that were behind where we were. This would
burn alot of cpu and when a stream had lots of consumers and they shift
leadership this would introduce some instability due to all the cpu
cycles.
