…elastic#54420) * Remove Redundant Cluster State during Snapshot INIT + Master Failover Similar to elastic#54395 we know that a snapshot in INIT state has not written anything to the repository yet. If we see one from a master failover, there is no point in moving it to ABORTED before removing it from the cluster state in a subsequent CS update. Instead, we can simply remove its job from the CS the first time we see it on master failover and be done with it.

Similar to #54395 we know that a snapshot in INIT state has not
written anything to the repository yet. If we see one from a master
failover, there is no point in moving it to ABORTED before removing it
from the cluster state in a subsequent CS update.
Instead, we can simply remove its job from the CS the first time
we see it on master failover and be done with it.
backport of #54420
Note: for the backport we need to keep the cleanup code because in a mixed cluster containing 6.x we could have still written data to the repo on INIT so we set the flag for the cleanup to true on the bwc path
