Share groups (since API v2.31)
==============================
The share groups enable you to create a group of volumes and manage them
together. A project can put shares be used in the same application together
in a share group, such as consistency group snapshot, clone, backup, migrate,
replicate, retype, etc.
Shares should be able to become a part of a share group only on share creation
step. If share was created without provided ``share_group_id`` then this share
won't be able to become a part of any share group.
You can create a share group and associate it with multiple shares, list
share groups, and show information for delete a share group.
.. note::
Share Group APIs are part of the `experimental APIs
<http://developer.openstack.org/api-ref/shared-file-systems/#experimental-apis>`_.
The ``availability_zone_id`` and ``consistent_snapshot_support`` fields were added
to ``share_group`` object introduced in version 2.34.
