    tests: run the show_highstate tests in parallel
    
    Instead of running the show_highstate tests one after the other, it is
    actually faster to run them in parallel for each of the OSes. Also, for
    the upstream formulas we run the tests only against the latest Leap OS,
    it doesn't make much sense to run them against everything
