xing-yang 708b9be9c0 Add group snapshots - APIs
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>
