Adding mock-detached util function and cleaning up util help output

- mock-detached will add or remove firewall rules to block
  traffic that would pull resources from the internet durning a deploy
  These firewall rule may need to be added to, just starting with
  http and https traffic figuring that would block the majority of cases.

- making updates to util help message according to:
  https://en.wikipedia.org/wiki/Usage_message
