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

- Update mon PDB to use maxUnavailable=1 instead of minAvailable. The maxUnavailable will always be 1 irrespective of the number of mons in the cluster
- Move mon PDB reconcile logic from Disruption Controller to Cluster Controller

Some settinc controller reference code can be replaced
with `controllerutil.SetControllerReference`. It's better to use it
since it provides ownerReference verification.

This PR makes create and delete events on pdb a no-op. Update event only triggers reconcile if its the main OSD pdb and allowed disruptions is 0.
This prevents controller to reconcile on pdb events namespaces outside rook ceph.

If the ceph cli outputs an error with "error calling conf_read_file"
this means that the operator has not written its ceph configuration
file. Thus ceph cli commands will fail, so we can just ignore that since
the operator will soon write this file in its initialization sequence.

If there is a single mon, we don't expect the PDBs to be created
and neither do we need to log that it is an error condition.

Currently the reconcile of the clusterDisruption controller was triggered mainly due to the
ceph status update in the cephCluster CR. This PR adds reconciles the cluster when:
1. Reconcile when the cluster is created. (This will trigger the first reconcile)
2. Reconcile only when the clusterSpec is updated. (This will avoid triggers when cluster status is updated)
3. Reconcile for events on cephblockpool, cephfilesystem and cephObjectStore.
4. Reconcile for events on Main PDB and when `DisruptionsAllowed` is 0. (that is, when one of the OSD goes down).
5. Reconcile after 30 seconds when there is an active drain going on, that is, pdbStateMap has `draining-failure-domain` as not empty.

-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

To provide more context for executing commands in a ceph cluster,
the full clusterInfo is now passed to the ceph execution commands.
All information about the cluster will now be available throughout
all the areas of the operator. The namespace, ceph credentials,
mon endpoints, and other info is a core part of that cluster info.
Arguments passed through the controllers are also simplified for
mons, mgr, osds, and other daemons where the parameters had
become too complex.

This is the final conversion to controller-runtime conversion. This time the
CephCluster CRD has been converted to use the controller-runtime
library.
The controller incorporates all the previous watchers too, so the Node
and hot-plug configmap are been watched too.
Only the operator setting configmap is not being watcher since it's not
related to the CephCluster CRD.
Not only the patch converts to controller-runtime but also tries to
re-organize the tree of the repo to actually make the code more
readable and have better functions/methods/tests separations.

The OSDs pick up on several topology labels for CRUSH hierarchy.
The GA label topology.kubernetes.io was partially implemented, but
not picked up by the OSDs. Now the OSDs will pick up both the topology
labels from pre-1.17 such as failure-domain.beta.kubernetes.io/zone
and topology.kubernetes.io/zone.

Description of your changes:
Fix security issues identified by TrailOfBits
Modifications in osd/status.go:
I opted by remove the offending variables because "c.checkNodesCompleted"
provides this variables always, so no need to initialize them.
var was not used, so i have replaced it by the blank identifier.
Modifications in machinelabel/add.go:
I have followed the same criteria used in other disruption packages,
and return the error if it is produced when we try to "watch" machines.

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.

WriteConnectionConfig() is called after the controller starts and thus
the 'osd find' command fails to complete because there is no ceph.conf
or key on the operator.
Let's skip this error print if that's the case since it's misleading and
polluting the logs.

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.

- Implement exportable TolerationSet with the following differences:
- Change map key to a string to ensure it is deterministic.
The old key was a struct that included a pointer.
- Sort the outputted list by this key to ensure the order is deterministic.
- Get the tolerations from the deployment instead of the pod as pod tolerations
are sometimes modified by the system. We only want user provided tolerations
in our deployment.
- Modify tests to try duplicate keys from different structs. The old way tested duplicate
keys using the same structs.
