allow nats service annotations about k8s

[caleblloyd]

you can merge/patch any k8s yaml right in:

service:
  merge:
    metadata:
      annotations:
        your-annotation: here

Full reference of resources that support merge/patch: https://artifacthub.io/packages/helm/nats/nats#values

@caleblloyd what if the value of this has to use $.Values? eg

your-annotation: {{ $.Values...}}

https://artifacthub.io/packages/helm/nats/nats#templating-values

example:

service:
  merge:
    metadata:
      annotations:
        your-annotation:
          $tplYaml: |
            {{ $.Values.myValue }}
