Avoid daemon forking with systemd

Browse source 
systemd units allow to run processes in foreground while daemonization is done on systemd service level when using Type=simple (default). This allows systemd to reliably track the service state, signals and could catch outputs, i.e. it is possible to remove "--quiet" to have Tautulli logging to systemd journal (journalctl) additionally or alternatively to log files.

In case of Type=forking, a PID file is required to allow system reliably determine the service state, which would be an alternative, but has no real advantage. The solution with "GuessMainPID=no" allows systemd to correctly determine the service active state, but e.g. when it is killed, it is seen as "Succeeded." since systemd cannot track the exit code or signal.
