    Fixes an issue with asynchronous deploy steps that poll for completion
    where the step could fail to execute.  The ``deployment_polling`` and
    ``cleaning_polling`` flags may be used by driver implementations to signal
    that the driver is polling for completion.  See `story 2003817
    <https://storyboard.openstack.org/#!/story/2003817>`__ for details.
