Custom Annotations for GRPC Service resource

[zimmertr]

Is your feature request related to a problem?

The optional Service resource that is created for handling ingress GRPC traffic does not expose a helm template to provide custom Annotations. This should be possible as other software often uses Annotations to dynamically configure features. For example, DataDog's Service Checks: https://docs.datadoghq.com/containers/cluster_agent/endpointschecks/?tab=datadogoperator#configuration-from-kubernetes-service-annotations

Describe the solution you'd like

  {{- with .Values.server.ingressServiceGrpcOrSomeOtherName.annotations }}
  annotations:
    {{- range $key, $value := . }}
    {{ $key }}: {{ $value | quote }}
    {{- end }}
  {{- end }}
