This commit adds code to supply variables required
to enable read affinity for rbd volumes.
It leverages `read_from_replica=localize,crush_locations=key:value`
krbd map option from ceph to serve reads from the most local OSD.

The built-in pools device_health_metrics and .nfs created by ceph
need to be configured for replicas, failure domain, etc.
To support this, we allow the pool to be created as a CR.
Since K8s does not support underscores in the resource names
the operator must translate this special pool name into
the name expected by ceph.
This also sets the basis for allowing filesystem data
pools to specify the desired pool name instead of requiring
a generated name.

It's better to create PDB of RGW if ObjectStore's `instances` field is 2.
In the current implementation, at least three desired RGW instances are needed
to create this. If `instances` is 1, we can still safely skip the creation
of PDB because it's useless.

-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

In the case where the node disappears abrubtly,
there was nothing to trigger the nodedrain reconciler to clean up
the stale canary.

When using the "errors" package, using `%+v` (extended format),
each Frame of the error's StackTrace will be printed in detail.
Let's only print `%v` to print the error.
If the error has a Cause it will be printed recursively.
Basically `%+v` has been replaced with `%v` for all `error` type
interfaces, whether the logger is Info, Warning or Error.

The node labels were already supported for zones and regions to add to
the CRUSH map. Now all layers of the CRUSH map will be supported
with the new labels such as topology.rook.io/rack.
The labels will be detected at the osd startup time
similar to the zone and region labels already being detected.
