This is the fifth patch that implements the generic-volume-group
bluerpint. It adds APIs for group snapshots and create group
from source.
This patch depends on the fourth patch which implements group
snapshots support in the volume manager:
https://review.openstack.org/#/c/361376/
Client side patch is here:
https://review.openstack.org/#/c/329770/
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>
