    Consistency Groups

    This patch enables Consistency Groups support in Cinder.
    It will be implemented for snapshots for CGs in phase 1.

    Design
    ------------------------------------------------
    The workflow is as follows:

    1) Create a CG, specifying all volume types that can be supported by this
    CG. The scheduler chooses a backend that supports all specified volume types.
    The CG will be empty when it is first created. Backend needs to report
    consistencygroup_support = True. Volume type can have the following in
    extra specs: {'capabilities:consistencygroup_support': '<is> True'}.
    If consistencygroup_support is not in volume type extra specs, it will be
    added to filter_properties by the scheduler to make sure that the scheduler
    will select the backend which reports consistency group support capability.

    Create CG CLI:
    cinder consisgroup-create --volume-type type1,type2 mycg1

    This will add a CG entry in the new consistencygroups table.

    2) After the CG is created, create a new volume and add to the CG.
    Repeat until all volumes are created for the CG.

    Create volume CLI (with CG):
    cinder create --volume-type type1 --consisgroup-id <CG uuid> 10

    This will add a consistencygroup_id foreign key in the new volume
    entry in the db.

    3) Create a snapshot of the CG (cgsnapshot).

    Create cgsnapshot CLI:
    cinder cgsnapshot-create <CG uuid>

    This will add a cgsnapshot entry in the new cgsnapshots table, create
    snapshot for each volume in the CG, and add a cgsnapshot_id foreign key
    in each newly created snapshot entry in the db.

    New consistency group APIs

    In Kilo, two new APIs were added to support consistency groups
    in Cinder:
    * Modify consistency groups.
    * Create consistency group from a snapshot of a consistency group.
    This patch adds documentation for the new APIs.
