- quman's argument parsing now uses subparsers to allow for more actions than enable and disable
- added the show-disables action to quman
- added a test mode for the command line quman, that allows the user to test quman using quman's user interface
- renamed disable tag as disable id, as it's more meaningful (identfies a disable request)
- made user errors more user-friendly (ie not polluted with call stack)

Whith this feature, it's now possible to disable an entire queue (and not only one queue machine), with
```sh
quman d main.q --disable-tag admin.graffy.bug4242 --reason 'preparing cluster to shutdown for power shortage, see bug 4242'
```
- also replaced the term queue name with queue machine for clarity, now that we have both QueueMachineId and QueueId
