Pods with > 1 container making connections do not show any connections

I believe this is because they share a network namespace, so the endpoint cannot be attributed to a container, and we drop it.

So given a pod has a unique IP, we could do another conntracked edge join on the pod topology to fix this.

I was previously against doing this, but with the recent improvements to conntrack, it might be worth it.

We're hitting this visualising Weave Cloud, and just had reports from a third party that they are also hitting this and they want to use scope in their Dockercon demo. So I'd like to try and get a fix in for 0.16 tomorrow.
