    Adds support for building config drives. Starting with API version 1.56,
    the ``configdrive`` parameter of ``/v1/nodes/<node>/states/provision`` can
    be a JSON object with optional keys ``meta_data`` (JSON object),
    ``network_data`` (JSON object) and ``user_data`` (JSON object, array or
    string). See `story 2005083
    <https://storyboard.openstack.org/#!/story/2005083>`_ for more details.
