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.
