Commit Message

(2.15) [FIXED] Consumer peer set remapping (#8335)

When a stream's replica count is updated, durable consumers are meant to
auto scale with them if `num_replicas: 0` was set in the consumer
config. However, the `isAutoScale` variable also included named
ephemeral consumers in this auto scaling, whereas they aren't supposed
to do that. They'd still converge to the allowed replica count based on
the consumer migration code, but this PR fixes that by not needlessly
scaling up these consumers for them to then be migrated back down, which
results in noticeable churn.

Additionally, this PR refactors the 3 consumer peer set remap paths into
a single reusable method. Marked as 2.15 for the time being, since I'll
want to get rid of the `sysRequest` separately, since it requires an
unsafe JS release and re-acquire.
