lw-zte c7148b8048 [api-ref]Add replication_status(optional) to List groups with details response 
The response of "list groups with deatils" interface refers to
that of "show group details",whose response contains replication_status.
So it is nesscessary to add replication_status to the response of
"list groups with details", so that user can get replication information
directly instead of calling "show group details" interface again.

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.
List groups
