Automatic merge from submit-queue (batch tested with PRs 41984, 41682, 41924, 41928) RC/RS: Fully Respect ControllerRef **What this PR does / why we need it**: This is part of the completion of the [ControllerRef](https://github.com/kubernetes/community/blob/master/contributors/design-proposals/controller-ref.md) proposal. It brings ReplicaSet and ReplicationController into full compliance with ControllerRef. See the individual commit messages for details. **Which issue this PR fixes**: Although RC/RS had partially implemented ControllerRef, they didn't use it to determine which controller to sync, or to update expectations. This could lead to instability or controllers getting stuck.

This staging/src/k8s.io/client-go directory is the staging area of the client repo. It contains a versioned client, tools built around the client like the reflector, and all the client dependencies. The content will be periodically published to k8s.io/client-go repo.
The staged content is copied from the main repo, i.e., k8s.io/kubernetes, with directory rearrangement and necessary rewritings. To sync the content with the latest code in your local k8s.io/kubernetes, you need to run godep restore in k8s root directory, then run staging/copy.sh.
vendor/k8s.io/client-go is a symlink pointing to this staging area, so to use the packages in the staging area, you can import it as "vendor/client-go/", as if the client were vendored. The client will be vendored from k8s.io/client-go for real after the test matrix is converted to vendor k8s components.
