Allow apps to open UDP ports
Currently, app-containers can request to have TCP ports directly exposed, through the
tcpPorts manifest entry ( https://cloudron.io/documentation/developer/manifest/#tcpports ).
It would be great if it were possible to do the same for UDP ports.
My usecase is for the OpenVPN app. TCP-over-TCP is quite inefficient, especially on unreliable connections (like when the bandwidth is maxed out, or on mobile scenarios), so the best practice is to use an UDP VPN server whenever possible, which is not possible on Cloudron right now.
