.Ceph Monitors no longer crash when using `ceph orch apply mon <num>` command
Previously, when the command `ceph orch apply mon <num>` was used to decrease monitors in a cluster, the monitors were removed before shutting down in `ceph-adm` causing the monitors to crash.
With this fix, a sanity check is added to all code paths that check whether the peer rank is more than or equal to the size of the ranks from the monitor map. If the condition is satisfied, then skip certain operations that lead to the monitor crashing. The peer rank eventually resolves itself in the next version of the monitor map. The monitors no longer crash when removed from the monitor map before shutting down.
