Currently some of the imports of `apimachinery` use
`k8s.io/kubernetes/staging/src/k8s.io/apimachinery...`. Replace
these with `k8s.io/apimachinery`, as is in use throughout the rest
of the code base.

1. Create controllerrevisions (history) and label pods with template
hash for both RollingUpdate and OnDelete update strategy
2. Clean up old, non-live history based on revisionHistoryLimit
3. Remove duplicate controllerrevisions (the ones with the same template)
and relabel their pods
4. Update RBAC to allow DaemonSet controller to manage
controllerrevisions
5. In DaemonSet controller unit tests, create new pods with hash labels

Deployment should ignore Pods that don't match the selector, even if
they have a ControllerRef pointing to one of the ReplicaSets it owns.
The ReplicaSet itself will orphan the Pod as soon as it syncs.
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).
Deployments get cleaned up only when they are paused, they get scaled up/down,
or when the strategy that drives rollouts completes. This means that stuck
deployments that fall into none of the above categories will not get cleaned
up. Since cleanup is already safe by itself (we only delete old replica sets
that are synced by the replica set controller and have no replicas) we can
execute it for every deployment when there is no intention to rollback.

controller: set unavailableReplicas correctly when scaling down
```
deployment_controller.go:299] Error syncing deployment
e2e-tests-kubectl-2l7xx/e2e-test-nginx-deployment:
Deployment.extensions "e2e-test-nginx-deployment" is invalid:
status.unavailableReplicas: Invalid value: -1:
must be greater than or equal to 0
```
The validation error above occurs usually when a Deployment is
scaled down. In such a case we should default unavailableReplicas
to 0 instead of making an invalid api call.
