Individual implementations are not yet being moved. Fixed all dependencies which call the interface. Fixed golint exceptions to reflect the move. Added project info as per @dims and https://github.com/kubernetes/kubernetes-template-project. Added dims to the security contacts. Fixed minor issues. Added missing template files. Copied ControllerClientBuilder interface to cp. This allows us to break the only dependency on K8s/K8s. Added TODO to ControllerClientBuilder. Fixed GoDeps. Factored in feedback from JustinSB.
