Cause of corrupt databases if the services are restarted incorrectly,
the order and dependencies are adjusted. Now, the `netbox-rq` service
will be included in restarts of `netbox` and required for the WSGI
servers that it must running.
For these changes, the restart command of `__netbox` was adjusted. The
other ones where edited too, to use the same command.
All services now require redis and postgresql to be started before them
to prevent any start order issues.
If someone asked for what the RQ worker is required, see here:
https://netbox.readthedocs.io/en/stable/additional-features/webhooks/#webhook-processing
The wrapper service will "control" the services added from the
__netbox_* types to provide a general interface. This is more dynamic
than the alias approach used previously. Through this, it is possible
to handle multiple wsgi services for netbox - if this works ..

Because someone *want* to use something other than just gunicorn, it was
extracted to a own type. Because gunicorn is a bit deep in the netbox
installation process, it's a bit harder to isolate it.
`__netbox_uwsgi` will come, too.
