rbd: flatten image in CreateVolumeGroup

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.
