Revert working directory changes as the configuration file still needs
to be accessable. An absolute path would work, too, but it is not the
preferred way.
To still work with the python wsgi application, `--chdir` is used.
The `uwsgi-netbox` service now works, also the `netbox` wrapper service.
The PID file was removed from the Gunicorn service as it is not required
and a bit more efford to move it to `/run/` due to permissions.
Generally, all depend on `network.target` instead of
`network-online.target` now, and signals for reload, stop and kill were
added (especially required the uwsgi service).
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 ..
