Generic volume groups (groups)

Generic volume groups enable you to create a group of volumes and manage them together.

How is generic volume groups different from consistency groups? Currently consistency groups in cinder only support consistent group snapshot. It cannot be extended easily to serve other purposes. A project may want to put volumes used in the same application together in a group so that it is easier to manage them together, and this group of volumes may or may not support consistent group snapshot. Generic volume group is introduced to solve this problem. By decoupling the tight relationship between the group construct and the consistency concept, generic volume groups can be extended to support other features in the future.
