This caused a dependency chain reaction (sigh):
* All the k8s packages had to be fetched again. This in turn required:
* Pining github.com/docker/docker/pkg/parsers to
0f5c9d301b9b1cca66b3ea0f9dec3b5317d3686d to cirvumvent
https://github.com/kubernetes/kubernetes/issues/18774
* Update github.com/juju/ratelimit
* Make probe/kubernetes/client.go comply with API changes.
