[EKS] [request]: Expose built in Prometheus Metrics from kube-scheduler & kube-controller-manager

I have tried to installed the `kube-prometheus-stack` chart in my EKS environment and I am getting the error.

alert: KubeControllerManagerDown expr: absent(up{job="kube-controller-manager"} == 1)

alert: KubeSchedulerDown expr: absent(up{job="kube-scheduler"} == 1)

The other pods proxy, kubelet ... are monitored with success. I have open a ticket on aws support and after test the support reply : EKS does not have these metrics published. All the metrics you can get will be displayed based on Metric server responses. EKS will monitor the health of Control Plane using its own internal mechanism.
