Primary thing we'd get is that there's a cadvisor update that allows our prometheus install to actaully get container metrics again...

We also need to upgrade the pause container, since that has been moved from Go to C.

I've built and pushed docker-registry.tools.wmflabs.org/pause:3.0

I've also rebased our changes (with some squashing) from v1.2.4wmf4 to 1.3.0wmf4 (took a few tries!)

I think I'll wait for https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG.md/#known-issues-and-important-steps-before-upgrading to fill out before actually upgrading :) From reading through the entire changelog the Pause change seems to be the only issue, but I'd rather wait...
