Describe the feature

Currenty it's not possible to annotate the secrets created by the certificates.cert-manager.io resources of this Helm Chart.

This for example prevents to annotate the secret for usage with EmberStack's reflector. This overcomplicate things like copying the CA into other namespaces.

What would the new user story look like?

N/A

Expected behavior

Adding secretsTemplate support to the capsule-proxy Helm Chart, so the following is possible:

apiVersion: cert-manager.io/v1
kind: Certificate
...
spec:
  secretTemplate:
    annotations:
      reflector.v1.k8s.emberstack.com/reflection-allowed: "true"
      reflector.v1.k8s.emberstack.com/reflection-allowed-namespaces: ""

If you are open to PRs, I will gladly create one!
