OVN: add tcp_reset{} action support
tcp_reset action transforms the current TCP segment according to the
following pseudocode:
if (tcp.ack) {
tcp.seq = tcp.ack;
} else {
tcp.ack = tcp.seq + length(tcp.payload);
tcp.seq = 0;
}
tcp.flags = RST;
Then, the action drops all TCP options and payload data, and updates
the TCP checksum. IP ttl is set to 255.
Prerequisite: tcp
