Use apps/v1 Deployment/ReplicaSet in controller and kubectl

This updates the Deployment controller and integration/e2e tests to use apps/v1, as part of #55714.

This also requires updating any other components that use the `deployment/util` package, most notably `kubectl`. That means client versions 1.11 and above will only work with server versions 1.9 and above. This is well within our client-server version skew policy of +/-1 minor version.

However, this PR *only* updates the parts of `kubectl` that used `deployment/util`. So although kubectl now requires apps/v1, it still also depends on extensions/v1beta1. Migrating other parts of kubectl to apps/v1 is beyond the scope of this PR, which was just to change the Deployment controller and fix all the fallout.

```release-note
kubectl: This client version requires the `apps/v1` APIs, so it will not work against a cluster version older than v1.9.0. Note that kubectl only guarantees compatibility with clusters that are +/-1 minor version away.
