      '''
      A helper function which returns a dictionary of minion pools along with
      their matching result sets.
      Useful for developing other "survey style" functions.
      Optionally accepts a "survey_sort=up" or "survey_sort=down" kwargs for
      specifying sort order.
      Because the kwargs namespace of the "salt" and "survey" command are shared,
      the name "survey_sort" was chosen to help avoid option conflicts.
