earlier, for mds, when resource limit is not defined it has
default limit of `"mds_cache_memory_limit": "4294967296"`
even if resouce.request is defined.
Now, resource request will be given preference when both
request and limit is defined and if only limit is defined
it will be applied or otherwise.

The rook.io/v1 package was only an internal implementation detail and
does not have any CRDs that rely on it. The CRD deserialization should
handle the change in internal types without any issue. This separation
gives more flexibility for the storage providers to implement exactly
what is needed for their storage provider instead of forcing to use the
same types and risk affecting another storage provider.

By setting the working directory of a Ceph daemon to the log direcor
(which is bindmounted to the host), we can ensure that the coredumps
will be available.
On CentOS 7 **only**, the kernel is configured with:
```
cat /proc/sys/kernel/core_pattern
core
```
which means that the coredumps will end up in the process working
directory and will be named "core".
On CentOS 8, everything is different and this won't work but still
CentOS will be able to consume this and changing the working directory
is harmless.

You can now use Rook along with Multus. Multus must be up and running
and the right ressources must exist such as NetworkAttachmentDefinition
CR.
The Cluster CR spec has new fields to work with multus:
network:
provider: multus (or 'host' for hostNetworking)
selectors:
public: NetworkAttachmentDefinition name
cluster: NetworkAttachmentDefinition name
If only a single NetworkAttachmentDefinition is provided Rook will use
both anyway for the Ceph traffic.

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

us to set configuration flag per daemon in a centralized fashion. Let's
use it for Mimic and newer and keep the CLI flag of daemon startup for
older versions.

Also, this commit refactors some code and add methods that are unit
