Prometheus multiple instance ingress

By adding multiple instances in https://gitlab.com/gitlab-com/gl-infra/reliability/-/issues/16047

The ingress is not currently being deployed for additional instances.

Goals:

  • Determine if an ingress is really necessary

    • Not required by Thanos
    • It points to the SVC, so not very useful to troubleshoot specific pods
    • Can still be accessed by kubectl port-forward

  • In case it should be added:

    • Try reusing the BackendConfig and IAP
    • Template ingress in the default values-instances/values.yaml.gotmpl file.
