[network-manager-openvpn/dcbw/openvpn-restart: 2/5] core: fix protocol and port specified with remote address



commit ddd6876c0132798da99e16c25dc4120b570c4b8c

    core: fix protocol and port specified with remote address
    
    If the port and protocol were specified in the remote address
    option (eg, "host[:port[:proto]]") nm-openvpn-service still
    added explicit --proto and --port options later, which confused
    openvpn.
    
    Let the port/proto of the 'remote' take precedence, and fallback
    to using the separately configured port or protocol options if
    the 'remote' didn't specify any.
