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.

Sometimes the default 15s is not enough for timeout of ceph commands. For examples,
I encountered that `radosgw-admin` command took dozens of seconds under heavy load.

This allows the catch-22 situation where the filesystem cannot be
reconciled because there is no MDS but there is no MDS because the
operator has not reconciled the filesystem and brought up the MDS pods.
