Turn ec2metaproxy into a library?

[therc]

I brought up an use case for the proxy within Kubernetes. See comment at https://github.com/kubernetes/kubernetes/issues/14226#issuecomment-184328220

Would it be feasible or even OK to turn the proxy into a library that can run inside either the kube-proxy or kubelet daemons that run on every node in a Kubernetes cluster? My rationale is that it'd be one less daemon to set up/monitor/restart, plus it would allow for better integration. I'll open a separate issue for network=host containers.

Sounds ok to me, although I personally think it would be better to run it as a separate daemon. It would just take some shuffling of the code, I think.
