Travis Nielsen ff1ab64d8d ceph: skip reconcile events where the spec not updated
The controllers should ignore events for status updates. The reconcile
only needs to happen when the spec is updated or the resource is marked
for deletion. Otherwise, the controllers may stay in an update loop as
the reconcile events are triggered again every time there is a status
update during the reconcile.

Travis Nielsen eeb687ad14 ceph: log skipped reconcile based on ceph health
When the Ceph health is HEALTH_ERR the controllers will skip the
reconcile. With info level logging there needs to be an indication
of this decision to skip the reconcile, otherwise users will
wonder why their resources aren't being created.

Sébastien Han c5075d55d1 ceph: trigger update on child controllers
When the CephCluster CR gets updated with a new image version, we need
to notify the child controllers of that upgrade.
For this, we set a 'ceph_version' label on the CR itself which will
effectively trigger a reconcile based on an update event.
This needs to be revisited and see how we can make use of
`EnqueueRequestsFromMapFunc` which might be a better approach using
controller-runtime built-in.

Sébastien Han 7788901a88 ceph: add liveness probe to mon, mds and osd daemons
Now Kubernetes will perform liveness checks on mon, mds and osd daemons.
The command will:

* call the socket (check for existence)
* execute a command and check the return code (success if 0)

This handles the case where the daemon is stuck locally and
unresponsive. It's unlikely but not impossible.
These checks bring more robustness to the implementation.

rbd-mirror and nfs have been leftover for the following reason. The
rbd-mirror socket name is different from other daemons (could be fixed
though): /run/ceph/ceph-client.rbd-mirror.a.1.94362516231272.asok also,
the command to call would need to be changed from "status" to "rbd
mirror status" so we can keep this for a later.
The nfs ganesha has no socket only a PID file which doesn't mean much.
No PID means the process does not run so Kubernetes will already handle
this and the pod will crash loop.

Sébastien Han c84d66de1b ceph: controller, reconcile faster
Let's not wait for the CephCluster to be done reconciling but instead
check for the Ceph cluster status, if it's closed to "ok" then we
proceed so HEALTH_OK and HEALTH_WARN are accepted.

Sébastien Han 9f2867e12a ceph: separate controller for CephObjectStoreUser CRD
Now, the CephObjectStoreUser CRD is managed with the controller-runtime.
So the watcher is outside of the main controller reconciliation loop of
CephCluster which brings numerous benefit such as:

* having its own reconciliation loop
* won't block anything from the main CephCluster controller loop
* fast than waiting for CephCluster loop to completion
