The pg_autoscaler is always enabled by ceph and cannot be disabled.
In a previous PR the pg_autoscaler config was removed from the main example.
Now the remaining config for the pg_autoscaler is removed as well.

This fixes the the MultiClusterDeploySuite CI failure. The operator
is timing out waiting for the mgr deployments to be
ready, according to the WaitForDeploymentToStart() method. After
the reconcile times out after about five minutes, the next
reconcile succeeds since the wait is only done for new mgr
deployments.

When the active mgr changes, there may be user-created services

The cluster info is important context for the cluster controller to
create the cluster, and all the fields must be properly set.
A test cluster name was being set temporarily, resulting in
mons incorrectly getting the wrong cluster CR name. There is no
known issue from the temporary value, it was just exposed by
https://github.com/rook/rook/pull/8678 setting the value to a label.
Now the functions are more clearly named so only unit and
integration tests should be using the test value for the cluster
name where it is not important.

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.

Both `ExecuteCommandWithOutputFileTimeout()` and

creating/reading/removing files where the stream output of the command
can simply be used. So sticking with `ExecuteCommandWithOutput()` and
`ExecuteCommandWithCombinedOutput()` for reading outputs is sufficient.

When there are multiple mgr daemons, the mgr sidecar owns reconciling
the services for the active mgr. However, for efficiency the sidecar
only reconciles the services if the active mgr changes. Now the operator
will also reconcile the mgr services to ensure that services are re-created
after being deleted, or otherwise in an incorrect state.

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.

The mgr daemon may be failed over by ceph if the active mgr is not
responding and the standby mgr is available. If the active mgr changes
the services for the dashboard and metrics will be updated with a

traffic to the standby mgr or else they will be incorrectly redirected
to the active mgr.

We can now prioritize orchestrations on certain event. Today only two
events will cancel on-going orchestrations (if any):
* request for cluster deletion
* request for cluster upgrade
If one of the two are caught by the watcher we will cancel the on-going
orchestration.
For that we implemented a simple approach based on check points, where
we will check for a cancellation request in certain part of the
orchestration. Mainly before each mons/mgr/osds orchestration loops.
This solution is not perfect, but we are waiting for the
controller-runtime to release its 0.7 version which will embed context
support. With that we will be able to cancel reconciles more precisely
and rapidly.

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
