* Added a godep-update-k8s script for upgrading.
$ KUBE_VERSION ./hack/godeps/godep-update-k8s.sh
* Added client-go version ldflags to localkube and minikube. The
version package is now split in both kubernetes and client-go, so we
need to supply both ldflags.
* Change cross builds to use BUILD_IN_DOCKER
* Add a patch for kube-proxy
The setup of kube-proxy recently changed, making the registering of the
component config a fatal error instead of a warning. This patch
reverts it to be a warning, which is a no-op for us anyways since we
don't supply a config file.
