Is your feature request related to a problem? Please describe the impact that the lack of the feature requested is creating.

I wanted to add annotations to the headlamp service and i realised that unlike for other resources the values for it are not defined.

Describe the solution you'd like

I would like to have an option to provide these via values.yaml. For example like you can do for sa

{{- with .Values.service.annotations }}
annotations:
  {{- toYaml . | nindent 4 }}
{{- end }}

What users will benefit from this feature?

Anyone that wants to use annotations on a service, can be used for multiple solutions for example enabling 3 party tools.

Are you able to implement this feature?

Yes
