Helm Chart || ServiceMonitor || support of attachMetadata: node

[PowerSurj]

What would you like to be added: Capability to add node metadata e.g. node labels

Why is this needed: it would enable filtering of node metrics through node labels

Describe the solution you'd like
in servicemonitor.yaml include additional templating that can results with below

spec:
  attachMetadata:
    node: true

as for example see node-exporter
https://github.com/prometheus-community/helm-charts/blob/main/charts/prometheus-node-exporter/templates/servicemonitor.yaml

  {{- with .Values.prometheus.monitor.attachMetadata }}
  attachMetadata:
    {{- toYaml . | nindent 4 }}
  {{- end }}

we could then add node labels to kube_node_info
