[kube-prometheus-stack] cannot add the external nodes as targets to prometheus

[ikozar]

Describe the bug a clear and concise description of what the bug is.

I triied to set up value "endpoints" in "charts/prometheus-node-exporter/values.yaml", to add IP node_exporter deployed outside of the cluster, but it doesn't work

I was able to add an external node export after applying the following endpoint

apiVersion: v1
kind: Endpoints
metadata:
  name: my-prometeus-prometheus-node-exporter
  namespace: monitoring
  labels:
    app: prometheus-node-exporter
    heritage: Helm
    release: my-prometeus
    chart: prometheus-node-exporter-3.3.0
subsets:
  - addresses:
      - ip: <minikube node IP>
      - ip: <external IP>
    ports:
      - name: http-metrics
        port: 9100
        protocol: TCP

it made possible to getting metrics from external node too, but after some time the external IP was lost
