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 was the last remaining CRD to not use the controller-runtime
library.
Small additions were added with the transition:
* the Kubernetes Secret that contains the CephX key has now an owner
reference to the CephClient object
* the secret name is present in the Status field of the CephClient:
```
status:
info:
secretName: rook-ceph-client-glance
phase: Ready
```
The controller will reconcile on CR updates and also if the Kubernetes
Secret is deleted.

this commit handle golangci-lint linter errcheck.
`errcheck` - Errcheck is a program for checking for
unchecked errors in go programs. These unchecked errors
can be critical bugs in some cases
To see only staticcheck linter output
`golangci-lint run --disable-all -E errcheck`

Instead of setting the Phase of the CR once the reconcile is done, let's
actually set in from the healthcheck so it is more accurate.

The mon was starting with a partial spec. There was a race condition
that was causing incorrect initialization in the health check goroutine
that could remove a mon upon operator restart. Now the mon will be
properly initialized with the full spec.

To provide more context for executing commands in a ceph cluster,
the full clusterInfo is now passed to the ceph execution commands.
All information about the cluster will now be available throughout
all the areas of the operator. The namespace, ceph credentials,
mon endpoints, and other info is a core part of that cluster info.
Arguments passed through the controllers are also simplified for
mons, mgr, osds, and other daemons where the parameters had
become too complex.

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
```
