docs: Helper to recordStep, which takes in some result, and appends a time waited, if
  appropriate. If timeTook is greater than zero, some time was waited along with
  the action, and the returned result will reflect that
  
  @param actual   - the actual outcome from the check
  @param timeTook - how long something took to run, provide 0 if it was an immediate check, and actual
  will be returned unaltered
  @return String: the actual response, prepended with a wait time if appropriate
