@jdef
i believe all the changes here are going to be part of the upstream k8s-1.2 release. Will i be missing anything when building k8sm using upstream repo? Thanks.

@ravilr we've tried to follow a process of merging to master, then cherry-picking/backporting to our stable release fork.

the UI in this fork is different than what's in 1.2, but 1.2 is shipping with kube-dashboard now anyway

there's also a bandaid PR in this fork for an issue that hasn't been properly addressed here, but HAS been addressed in 1.2 and master (https://github.com/kubernetes/kubernetes/pull/18966/files?w=1)

the upstream/release-1.2 branch should not be missing anything
