The operator will now allow the resource limits to be applied below the
recommended minimums. In small clusters, even the recommended minimums
may not be necessary. A warning is still printed to the operator log,
but we allow the configuration to continue.

The labels cannot be updated on a deployment match selector.
In v1.4 a new label was added for ceph_daemon_type that is intended
to be on the pod labels, but cannot be applied to the match selectors.
Therefore, we suppress any new labels that are added to the daemons.

Rename PodLabels function to CephDaemonAppLabels for more clarity about
what the function's purpose is.

This can help users identify the daemon type similarly to how
'ceph_daemon_id' helps identify the daemon ID. This also makes it so
scripts users create don't have to parse "app=rook-ceph-<daemonType>"
into "<daemonType>" if they desire that bit of info.

The ceph config and client packages are conceptually the same.
To avoid circular dependencies in some cases, we simplify by combining
the packages into the client package.

The OSD daemon has been missing critical flags for logging to stderr
where k8s can capture the logs. Without the --log-to-stderr=true,
all the OSD logging was essentially lost until now.

When the cluster is loaded and we restart an OSD, it will need some time
to respond to socket calls, basically more to be ready.
Increasing the initialDelaySeconds of the liveness probe fixes that
issue. For OSD, it waits for 45 sec, where other daemons 10 sec.

This type was a string already and was just making us doing string()
calls all the time to it's not worth it.

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.

Now, the CephBlockPool 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
