> Add MiniOzoneCluster integration coverage for 5-node OM and SCM rings:
> * *TestOzoneManagerHAWithFiveNodes* (new): 5 OMs form one Raft group; writes
> reach all 5 OM DBs; leader transfer to a specific OM; stop the leader and a
> follower -> new leader, reads and writes work; stop a 3rd OM -> no leader for
> 3 election timeouts and writes fail; restart one -> quorum restored; restart
> the last 2 after the leader purged its log -> both install a checkpoint and
> converge; the ring survives another leader failure.
> * *TestStorageContainerManagerHAWithFiveNodes* (new): the same for 5 SCMs,
> plus every datanode has 5 SCM endpoints and every SCM sees all datanodes
> HEALTHY; container allocations and key writes reach all 5 SCMs.
> * *TestAddRemoveOzoneManager#testBootstrapToFiveOMsAndDecommissionToThree*
> (new): bootstrap 3 -> 5 OMs, stop 2 original OMs so the majority needs the
> votes of both bootstrapped OMs, decommission back to 3.
> * *TestSecretKeysApi#testSecretKeyAfterSCMFailover*: run with 3 and 5 secure
> SCMs, stop the leader (n-1)/2 times, and check every SCM certificate is
> issued by the shared root CA.
> Also fix {{MiniOzoneHAClusterImpl#stopSCM}}: it called
> {{stopAndDeactivate(StorageContainerManager)}}, which called {{stopSCM}}
> again, so it always failed with StackOverflowError. Nothing used it before.
> {{TestStorageContainerManagerHAWithFiveNodes#testStoppedSCMsCatchUpViaCheckpointInstall}}
> needs HDDS-16924: without it the test fails with ~12,000 "Rocks Database is
> closed" errors; with it the test passes.
