Implement automated CephX key rotation for OSDs.
OSDs have marshalled CephX statuses applied as an annotation on the OSD
pod spec, which differs from other Rook Ceph daemons for a two reasons:
A large cluster could have hundreds or thousands of OSDs, so it is more
critical that Rook avoid rotating OSD keys more than once in the event a
CephCluster reconcile restarts partway through OSD creation/updation.
OSDs do not have their CephX keys stored in K8s Secrets, whose resource
version is used for enforcing the desired restart behavior other daemon
pods like RGWs.
