UPSTREAM: proxy/iptables: Don't rewrite chains that haven't changed
e5a14b8 
iptables-restore requires that if you change any rule in a chain, you
have to rewrite the entire chain. But if you avoid mentioning a chain
at all, it will leave it untouched. Take advantage of this by not
rewriting the SVC, SVL, EXT, FW, and SEP chains for services that have
not changed since the last sync, which should drastically cut down on
the size of each iptables-restore in large clusters.
