ovs-ofctl: Add support for transport and network modification actions

Add support to ovs-ofctl for modifying the network source and destination
IP address with the "mod_nw_src" and "mod_nw_dst" actions, respectively.
And support modifying the TCP/UDP source and destination ports with the
"mod_tp_src" and "mod_tp_dst" actions, respectively.
