------------------------------------
As maintained in
[comment#6491,|https://github.com/apache/ozone/pull/6491#issuecomment-2272219528,]
we can keep the batch purge if we use a single map. Closing it for now and
will reopen it or create a new jira if we see any consistency issues even after
HDDS-11137/[#7018.|https://github.com/apache/ozone/pull/7018]
> Snapshot purge should be a atomic operation

> fails and leave it in a situation that snapshot's previous snapshot is

> Other thing is we may need locking in snapshot purge request handler.
