Add support for group snapshots
This patch adds support for group snapshots.
Server side API patch was merged:
https://review.openstack.org/#/c/361369/
Current microversion is 3.14. The following CLI's are supported:
cinder --os-volume-api-version 3.14 group-create-from-src
--name my_group --group-snapshot <group snapshot uuid>
cinder --os-volume-api-version 3.14 group-create-from-src
--name my_group --source-group <source group uuid>
cinder --os-volume-api-version 3.14 group-snapshot-create
--name <name> <group uuid>
cinder --os-volume-api-version 3.14 group-snapshot-list
cinder --os-volume-api-version 3.14 group-snapshot-show
<group snapshot uuid>
cinder --os-volume-api-version 3.14 group-snapshot-delete
<group snapshot uuid>
