wireguard: T3763: Added check for listening port availability
Each wireguard interface requires a unique port for in and out connections. This commit adds the new `vyos.util` function - `check_port_availability`, and uses it to be sure that a port that is planned to be used for wireguard interface is truly available and not used by any other services (not only other wireguard interfaces).
