Deployment: Use ControllerRef to list controlled objects.

Although Deployment already applied its ControllerRef to adopt matching ReplicaSets, it actually still used label selectors to list objects that it controls. That meant it didn't actually follow the rules of ControllerRef, so it could still fight with other controller types. This should mean that the special handling for overlapping Deployments is no longer necessary, since each Deployment will only see objects that it owns (via ControllerRef).
