Automatic merge from submit-queue. Map horizontal-pod-autoscaler-use-rest-clients flag Maps `--horizontal-pod-autoscaler-use-rest-clients` flag which is required for [Horizontal Pod Autoscaling][1]. See Kubernetes code in [kubernetes/kubernetes/blob/v1.7.11/cmd/kube-controller-manager/app/autoscaling.go#L36-L39][2]. Seems this is the missing piece for fulfilment of HPA pre-requisites, which are: * ✅ Enable the [Aggregation Layer][4] via the following kube-apiserver flags * ✅ `--requestheader-client-ca-file=<path to aggregator CA cert>` (see #3679) * ✅ `--requestheader-allowed-names=aggregator` (see #3679) * ✅ `--requestheader-extra-headers-prefix=X-Remote-Extra-` (see #3679) * ✅ `--requestheader-group-headers=X-Remote-Group` (see #3679) * ✅ `--requestheader-username-headers=X-Remote-User` (see #3679) * ✅ `--proxy-client-cert-file=<path to aggregator proxy cert>` (see #3165) * ✅ `--proxy-client-key-file=<path to aggregator proxy key>` (see #3165) * ❓ [Horizontal Pod Scaling][3] ... set the appropriate flags for `kube-controller-manager`: * ❎ `--horizontal-pod-autoscaler-use-rest-clients` should be `true`. * ✅ `--kubeconfig <path-to-kubeconfig>` (already set) **Relevant Documentation:** * https://v1-7.docs.kubernetes.io/docs/tasks/run-application/horizontal-pod-autoscale/ * https://v1-7.docs.kubernetes.io/docs/tasks/access-kubernetes-api/configure-aggregation-layer/ **Relevant Issues & PRs:** * #3679 * #3152 * #2691 * #2652 * #3165 [1]: https://v1-7.docs.kubernetes.io/docs/tasks/run-application/horizontal-pod-autoscale/ [2]: https://github.com/kubernetes/kubernetes/blob/v1.7.11/cmd/kube-controller-manager/app/autoscaling.go#L36-L39 [3]: https://v1-7.docs.kubernetes.io/docs/tasks/run-application/horizontal-pod-autoscale/ [4]: https://v1-7.docs.kubernetes.io/docs/tasks/access-kubernetes-api/configure-aggregation-layer/
