Add Pre-configured Tunnel

Pre-configured tunnels may be added as a separate service.

The service is set to automatic (delayed) as this will guarantee the service starting if the network is not available when the service first starts. This mainly happens due to a very large hosts file or network being unavailable at boot.

# Install my-tunnel.conf as a startup tunnel (powershell as admin).
