openvswitch: support asymmetric conntrack
The openvswitch module shares a common conntrack and NAT infrastructure
exposed via netfilter. It's possible that a packet needs both SNAT and
DNAT manipulation, due to e.g. tuple collision. Netfilter can support
this because it runs through the NAT table twice - once on ingress and
again after egress. The openvswitch module doesn't have such capability.
Like netfilter hook infrastructure, we should run through NAT twice to
keep the symmetry.
