      Runs a RightScript and polls for status.
  
      Sample usage::
  
          from rightscale import run_script_on_server
          run_script_on_server(
                  'my cool bob lol script',

                  inputs={'BOB': 'blah blah', 'LOL': 'fubar'},
                  )
  
      Sample output::
  
          status: Querying tags
          status: Querying tags
          status: Preparing execution
          status: RightScript: 'my cool bob lol script'
          status: completed: my cool bob lol script
  
      Defaults to printing status message to stdout, but will accept any object
      that implements ``write()`` passed in to :attr:`output`.
