docs: Ensure user has set required values in weather.ini.
  
          Normally the :py:data:`~ServiceBase.config` names with
          ``required`` set are checked, but if your uploader has a
          ``register`` method you may need to check for other data.
  
          :param str keys: the :py:data:`~ServiceBase.config` names to
              verify.
