BenTheElder 1f6baa6549 Move userspace code to sub-package in proxy.
Moves the userspace code in proxy to a sub-package and adds the
ProxyProvider interface.

This is in preparation for landing an implementation of
https://github.com/GoogleCloudPlatform/kubernetes/issues/3760, which
will mostly be in another sub package for iptables.
