There is no need for the `Manager.DeleteVolumeGroup()` function as
`VolumeGroup.Delete()` should cover everything too.
By moving the `.Delete()` functionality of removing the group from the
journal to the shared `commonVolumeGroup` type, a volume group snaphot
can use it as well.

This commit adds support for flattenMode option
for volumegroup.
If the flattenMode is set to "force" in
volumegroupreplicationclass parameters,
cephcsi will add a task to flatten the image
if it has parent before adding it to the group.
This enable cephcsi to then mirror such images
after flattening them.

The ModifyVolumeGroupMembership operation can be used to change the
volumes that are part of a VolumeGroup. Only empty VolumeGroups can be
removed, this operation is required to make that possible.

Add extra error checking to make sure trying to create an existing
volume group does not result in a failure. The same counts for deleting
a non-existing volume group, and adding/removing volumes to/from the
volume group.
