Soam Vasani 40dfba1a41 Switch to official Kubernetes Go client -- client-go/1.4
Switch to client-go package instead of pulling the from kubernetes.
Use a versioned client with sensible compatiblity.

This change breaks 'go get'.  For now you have to manually checkout
the 'release-1.4' branch of the client-go package after 'go get'
fetches it.  TODO: use one of the build tools to fix this.
