Gaetan Boisson 6657860010 Bug 11417: make sure remove_unused_authorities.pl accepts --test
This patches adds support for the --test option, as well as a
short message telling the user the script is running in test mode.

Test plan :
- Launch the script with -h to see the help
- Launch the script with --test and --aut with an authtypecode
  that is used in your instance
- Make sure it does the same thing as launching it with -t
- Launch the script for real and make sure it still works as
  expected, deleting unused authorities.
