This change is the solution to resolve the scenario where after
an uncontrolled swact due to killing one of the critical processes
twice, the ceph-mon service doesn't start in the new active
controller occasioning a new swact.
It was created a flag to signalize a complete shutdown of ceph-mon.
After an uncontrolled swact, the system verifies if the flag
exists, and if so starts the ceph-mon service in the new active
controller.
Test Plan:
PASS: System host-swact.
PASS: Ceph recovery after rebooting the active controller.
PASS: Ceph recovery after uncontrolled swact killing a critical
process twice.
PASS: Ceph recovery after mgmt network outage for a few minutes
even when rebooting controllers.
PASS: Ceph recovery after case of dead office recovery (DOR).
PASS: Upgrade success from stx 7.0 to 8.0 in a duplex lab.
