This patch adds `pgHealthyRegex` field to DisruptionManagementSpec.
`pgHealthyRegex` is a regular expression that is used to determine which
PG states should be considered healthy. The default value of
`pgHealthyRegex` is:
^(active\+clean|active\+clean\+scrubbing|active\+clean\+scrubbing\+deep)$
which is effectively the same as before.

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.

Rook checks for down OSDs by checking the `ReadyReplicas` count
in the OSD deployement. When an OSD pod goes into CBLO due to
disk failure, there is a delay before this `ReadyReplicas` count
becomes 0. The deplay is very small but may result in rook missing
OSD down event. As a result no blocking PDBs will be created and
only default PDB with `AllowedDisruptions` count as 0 is available.
This PR tries to solve this. The OSD pdb reconciler will be
reconciled again if `AllowedDisruptions` count in the main
PDB is 0.

Both `ExecuteCommandWithOutputFileTimeout()` and
`ExecuteCommandWithOutputFile()` generate unnecessary system calls by
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.

This PR has following changes around OSD pdbs
- Detect node drains more reliably. When OSD is down and OSD pod is not scheduled to any node or if the scheduled node is not ready, then assume that node is draining.
- Don't set no-out flag on the failure domain if the OSD is down due to reasons other than node drain (say disk failure)
- update unit tests
- update design doc to reflect above changes

-creates a single PDB (max-unavailable=1) for all OSDs. This PDB allows one OSD to go down at a given time.
-When a drain is detected, blocking PDBs (max-unavailable=0) will be created for each failure domain that is not being drained and the main PDB (max-unavilable=1) will be deleted. This will allow all the OSDs in the currently drained failure domain to be removed while blocking the deletion of OSDs in other failure domains.
-Once the PGs are healthy again, the blocking PDBs will be deleted and the main PDB will be restored.
-Add PG healthcheck timeout
-Delete any legacy node drain pods and blocking OSD PDBs
