Refactor ControllerRefManager
**What this PR does / why we need it**:
To prepare for implementing ControllerRef across all controllers (https://github.com/kubernetes/community/pull/298), this pushes the common adopt/orphan logic into ControllerRefManager so each controller doesn't have to duplicate it.
This also shares the adopt/orphan logic between Pods and ReplicaSets, so it lives in only one place.

Make controller-manager resilient to stale serviceaccount tokens
Now that the controller manager is spinning up controller loops using service accounts, we need to be more proactive in making sure the clients will actually work.
Future additional work:
* make a controller that reaps invalid service account tokens (c.f. https://github.com/kubernetes/kubernetes/issues/20165)
* allow updating the client held by a controller with a new token while the controller is running (c.f. https://github.com/kubernetes/kubernetes/issues/4672)
