Split Server Service Annotations Between Internal & Not

[rfpludwick]

Is your feature request related to a problem? Please describe.

I am using external-dns to expose services in my k8s cluster to Pi-holes. Vault is one of those services. I am using the following YAML values for the Helm chart:

server:
  ingress:
    enabled: true
  service:
    annotations:
      external-dns.alpha.kubernetes.io/hostname: "vault.k8s-cluster.local"

This annotation is getting applied to both the vault-internal and vault services. It's causing issues with external-dns and is ending up setting the DNS to 10.* addresses, rather than the 192.168.* address I would be expecting.

Describe the solution you'd like

Feature request: please split the annotations which get applied to these two services, that way I can specify an annotation just for the vault service. Possible YAML values structure could be:

server:
  service:
    internal:
      annotations: {}
    external:
      annotations: {}

Describe alternatives you've considered

I've been unable to determine any alternative action I can take.
