    Update Pure replication to cheesecake

    Migration to cheesecake replication. This basically
    modifies any of the existing replication code to work on the whole
    backend instead of the specified volume.

    It also completes the transition to allow swapping the underlying array
    being managed by cinder upon failover. In the v2 implementation it was
    conditional on some operations where things *could* be on the other
    array. Now it is all driver operations.

    This also switches the target_device_id to backend_id in the config for
    replication devices.
