----------------------------------------
Related jira: RATIS-1884, RATIS-2152.
It is also possible that we need to:
(1) reduce key deleting service interval
(2) increase max open fd to 1 million (currently at 100k)
(3) throttle key deleting service (we have
ozone.snapshot.deleting.limit.per.task which is at 10)
(4) max open file per rocksdb ozone.om.snapshot.db.max.open.files (default =
100)
> OM crashed in the Snapshot scale test exceeding 100,000 open fd
