During cluster deletion, we currently only retry for a couple minutes
to wait for the pvcs to be deleted. After the timeout, we proceed
with the cluster deletion. To properly protect the pvcs for proper
cleanup, the finalizer should not be removed until the pvcs
are all confirmed to be deleted. In order to not block other cluster
events, we re-queue the deletion event to run again every 10s
until the pvcs are deleted or the finalizer is manually removed.

The controller setting for requeuing an event moved to the
opcontroller package and was no longer needed in the main
controller package.

This is the final conversion to controller-runtime conversion. This time the
CephCluster CRD has been converted to use the controller-runtime
library.
The controller incorporates all the previous watchers too, so the Node
and hot-plug configmap are been watched too.
Only the operator setting configmap is not being watcher since it's not
related to the CephCluster CRD.
Not only the patch converts to controller-runtime but also tries to
re-organize the tree of the repo to actually make the code more
readable and have better functions/methods/tests separations.

The name of a CephCluster is commonly the same as the namespace,
but not always. When looking up the ceph cluster we can look for
the first one in the namespace rather than requiring the name
to be the same as the namespace.

Previously, the rbd-mirror daemon was integrated into the `CephCluster`
CRD. This wasn't really practical since we would have to wait for the
whole orchestration to be done to actually set it up. The same goes for
any CR update. Let's say you want to change the number of daemons, Rook
would go through mons, mgrs and osds until it get to rbd-mirror.
This triggers an undesired full orchestration.
With its own CRD this component just gains a lot more flexibility.

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.

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.

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.

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.

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.

This brings robustness in our operator, meaning that any resources that

The ceph commands are now only written to the log in debug mode.
For commands that change the system state we now ensure that
a useful log entry is written. If all the details of the ceph
commands are needed, debug logging should still be enabled.

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
