Update backend kubernetes client dependencies to newest HEAD

[floreks]

As we want to support PetSets, kubernetes client dependencies need to be updated. There are issues with godep because our import path is different than our backend code path and I couldn't find a way to update them using godep, so I've updated it manually.

Checkout and test it please as also our code needed some changes.

If anyone knows a way to update everything correctly with godeps, it would be great.

Go tests need to be fixed. Do not merge.
