Collect MKE cluster metrics with metrics-server

Mirantis Kubernetes Engine (MKE) can deploy and manage the optional upstream-compatible Kubernetes metrics-server component.

With metrics-server enabled and reconciled, kubectl top nodes and kubectl top pods use live CPU and memory metrics.

MKE runs metrics-server in the kube-system namespace, configures TLS for the extension API by using an APIService with a CA bundle, and provisions kubelet CA material so that metrics-server can securely scrape kubelets.
