Tested Kubernetes driver against a real kubernetes cluster deployed for the tests. Worked properly.

Since I started to work on this PR, we've revamped at multiple occasion the architecture of the scalable Async RPC. We ended up on something really different that what was first envisioned.

Closing this PR in favor of a one against with a new branch.
