[Review] Request from 'tgoettlicher' @ 'SUSE/machinery/review_141002_workflow_hints'

Please review the following changes:
  * 233481e Added work flow hints
  * 21c7a9f Merge branch 'remove_primadonnas'
  * a2f759b Get rid of prima donna methods
This would be cleaner as `Hint.how_to_show_data(:name => name)`
