ceph-volume now sends status and log output to stderr, which breaks
`ceph-volume lvm prepare` if not other things as well. Use the combined
stdout and stderr output from ceph-volume to fix this.

Add support for MachineDisruptionBudget controller and MachineLabel controller required for fencing
in OpenShift. This will ensure that machines are only fenced and OSDs are only stopped
when Ceph is in a healthy state.

Some users have reported issues running Ceph OSDs in environments
without beefy systems. After consulting with Ceph experts, we believe
2Gb is still a safe minimum for Ceph for users with more modest systems
that won't result in disfunction in Ceph.

After further consideration and working with the feature for a few
weeks, the `configOverride` functionality seems to be more complexity
than is worth it for the expected benefit. Users still have the most
preferred option of setting configs in Ceph's config database using
`ceph cofig set` or the dashboard, and the override ConfigMap still
exists for fallback scenarios. The config database can still be used
by Rook for setting necessary configs, but the user has no way of
telling Rook to do so.

OSD pods when running on PVC fail randomly due to some race condition:
- OSD daemon pod was activating the volume group using vgchange -an without any volume group name.
- This caused the pods to fail randomly when number of OSDs is more, say greater than 10.
- This fix adds Volume group name while activating/deactivating volume groups to fix this

Reduce the duplication of detecting the version of the external cluster
by refactoring to a single method that retrieves and validates the
version

Add various upgrade tests so that the local cluster does not fail if
an upgrade is available on the external cluster.
Also, add better upgrades handling on update and on add. We now rely as
much as possible on a unique function that works both local and external
cluster 'detectAndValidateCephVersion()'. So the code will act the same
way wether a CR update is triggered or if the operator is restarted.
The health check now reports any topology changes on the external
cluster such as odd number of mons and low number. It will also detect
if the external cluster has been upgraded and will log that information,
helping the admin in his/her decision to trigger an image upgrade.
Finally, we prevent the creation of new CRs if the external cluster
version has a higher major number than the local one.

The log messages for orchestrations being skipped due to nodes still
being schedulable or unschedulable is filling the logs and not necessary.
The log message for reconciling is now debug, and also fixed another
formatting log message.
