Title: initial commit for map runner

This pull request adds a general purpose map/reduce style salt-runner for aggregating identical results returned by several different minions.
Aggregated results are sorted by the size of the minion pools returning identical results.

This is useful for playing the game: " some of these things are not like the others... " when identifying discrepancies
in a large infrastructure managed by salt.
