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.

when running OSD on PVC, orchestration should not be started again if there is any change in the device config
map. Added a check to skip orchestration on device CM update when StorageClassDeviceSets are available,
that is, when running osd on pvc.

If the cluster has previously been initialized and the operator
is restarted, the operator needs to perform the first orchestration
to confirm basic cluster health, then start watching for CR events.
If there was a single mon pod in a failed or pending pod state, the
orchestration was blocked even if just one mon was in this state.
The scenario is when a node is lost and a mon and the operator happen
to be running on that node. The operator will restart, but the mon
will not restart because it is tied to the node that died (unless running
on a PVC). The mon would remain in a pending state while attempting
to schedule on the node that is down indefinitely and the operator would
be blocked indefinitely. Now we will just log the error and attempt
to continue.

Some testing on OpenShift has shown that enabling Hostnetworking causes
issues with ceph-volume creating OSD.
This is a pure Red Hat OpenShift downstream issue.
This is meant to be temporary while we are waiting for the Selinux team
to get back to us.

Generating keyrings after deployments created a race condition
resulting in intermittent OSD pod failure on the first attempt.
This change creates keyrings prior to creation of OSD deployments
and updates the owner after the creation of a deployment.

If a volume is being attached, it should be verified that the volume
is safe to attach. The volume was assumed to be safe to attach if it was
for the same pod. But this was assuming the pod of the same name would be
on the same node. This is true for pods created from deployments, but not
for pods that are part of a stateful set. A stateful set will maintain the
pod name even as the pod is failed over to a new node. Therefore, the fencing
much check if the pod is from the same node before allowing the attach to
continue. Otherwise, we need to wait for the volume to be detached from the
other node.

This will be helpful to list the CSI drivers deployed
in the kubernetes cluster. if we have N number of
CSI drivers deployed in the cluster, the user can
query kubectl get csidriver and get the list of
registered CSI drivers and it requires kube 1.14+
and also the functionality is disabled by default

In Octopus, this commit
https://github.com/ceph/ceph/pull/30859/commits/c09b82a80a392ccd0da7677c7b424ce5cd3fa5d6
moved the quorum_status command to a socket call. Thus, the `ceph
quorum_status` command does not exist anymore, to use it we need to do
`ceph daemon mon.$ID quorum_status`. However, this command only works
locally so it won't work if we run it from the operator.
The `ceph mon_status` command is a general command that run from
anywhere and returns the mon map, let's use this one on the operator
code.
This is not a breaking change.

Even legacy osds were still running with this flag. In my previous patch
I was trying to minimize the impact of the change and was afraid the
config file was holding important information but that appears not to be
true.
The only option in the config could have the keyring path, but it's
passed in the CLI startup line.

The mgr modules take some time to run and have also been known
to hang. While the hang issues should have been resolved separately,
an improvement is still to allow the configuration to happen
in parallel for unrelated modules. All of the module configuration
will be completed before continuing with osd configuration
in order to keep the logging simpler.

OSD on PVC does not upgrade when the user upgrades the ceph version on cluster-on-pvc yaml.
The solution incudes:
- upgrade osd prepare and daemon pods on upgrade
- skip c-v prepare if filesystem is already present on the pvc device.
- skip lvm release in case of upgrade.

If mon deployments need to be created, the operator should
go ahead and create all of them instead of waiting for quorum
in between checking each mon. In particular, if a cluster is
being restored in a disaster recovery situation, none of the mons
deployments will exist. All of them should be created before
checking for quorum.

When both PARTNAME and ID_PART_ENTRY_NAME are specified, rook takes
PARTNAME in account, overriding ID_PART_ENTRY_NAME. As PARTNAME is not
always updated by the kernel after sgdisk --change-name, it's better to
do the opposite. It also makes GetDevicePartitions coherent with
parsePartLabel (called by GetPartitionLabel).
