Update master branch to Kubernetes v1.14

[alexbrand]

The v1.13.x branch tracks the 1.13 release of Kubernetes.

The master branch should track the v1.14 release.

I'd love to tackle this issue if it's still relevant

@flostadler This is definitely still relevant. AFAICT, there are only a couple of issues that need to be resolved: #196 (which is potentially fixed via PR #197) and making sure the Docker daemon uses "systemd" for the cgroups driver instead of "cgroupfs" (an issue I've observed but have not yet opened an issue for---I'll remedy that shortly). What can I do to help you get started on this issue?

[scottslowe]

We should also resolve #198 before branching for 1.14 (this is the cgroups driver issue mentioned above).

[flostadler]

@scottslowe Anything to look out for, or some common pitfalls?

[scottslowe]

@flostadler I don't think so. We're still working on documentation, so if you run into any problems or have questions, please don't hesitate to contact me (or one of the other contributors).
