The CSI package needs to load clusterInfo, today this code is in the mon
package which makes the call of LoadClusterInfo impossible without
having a circular import.

Rook does not support running multiple clusters in the same namespace,
so the operator should not reconcile if a new cluster is added.
The scenario where a cluster is added while the operator is down is also
handled. CR updates are also handled.
When the operator detects more than one cluster it will refuse to
reconcile the CephCluster, and child CRDs will block too until the
operator is ready.
The user must remove one of the clusters before can continue to perform
any reconcile.

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.
