Consistent Group

For a group to support consistent group snapshot, the group specs in the corresponding group type should have the following entry:

{'consistent_group_snapshot_enabled': <is> True}

Similarly, for a volume to be in a group that supports consistent group snapshots, the volume type extra specs would also have the following entry:

{'consistent_group_snapshot_enabled': <is> True}
