    bin/test_show_highstate.py: various improvements
    
    - add ability to run the script as non root with sudo where needed
    - add ability to run against multiple operating systems and make it run
      against each declared OS and each declared location combination
    - print the OS and location that it is running against
    - do not fail when a show_highstate command fails. Instead, let them all
      run with various combinations to show the user all the errors, and
      exit with the appropriate status code
