This commit is a large refactor on how the operator starts, stops and
how it starts various sub-components such as the ceph-csi driver. It
also refines the way we cancel orchestrations. We don't use breakpoints
anymore but send our self a SIGUP to reload our controller runtime
manager.
The reload will happen under different circonstances like:
* a new adminission controller secret is created/deleted/changed
* a CephCluster CR is edited
As mentioned earlier, the csi driver now has its own controller, just
like flex. It reacts to change in the operator config map for particular
ROOK_CSI_ fields.
A second new controller for the operator's general config has been
created, it manages:
* the logging level
* the ceph CLI command timeout
* the discovery daemon
The operator reacts much more rapidly to cancellation events by stopping
the manager's context and reloading it.

This commit allows us to configure status check for each daemon:
* "mon": health check on the ceph monitors (quorum)
* "osd": health check on the ceph osds
* "status": ceph health status check
Each check is controlled by the following settings:
* disabled: whether to disable the check (default: false)
* internal: interval to run the check
* timeout: only valid for mons, is the timeout for unresponsive mon
before failling over.
Example to disable the status health check:
```yaml
healthCheck:
daemonHealth:
status:
disabled: true
```
As part of that, pod's livenessprobe can now be configured via the
following settings:
* disabled: whether to enable or not
* probe: override the current probe in place by a new one
```yaml
healthCheck:
livenessProbe:
mon:
disabled: true
```
