Update the Deployments' API types, defaulting code, conversions, helpers and validation to use ReplicaSets instead of ReplicationControllers and LabelSelector instead of map[string]string for selectors. Also update the Deployment controller, registry, kubectl subcommands, client listers package and e2e tests to use ReplicaSets and LabelSelector for Deployments.
