What would you like to be added:
We would like to use cert manager with our metrics endpoint.

Why is this needed:
Metrics are only secure by using https and requiring the service account access.

We want to make sure that our metrics endpoint has tls options as this is a recommended approach for our organization.

Plan:

https://book.kubebuilder.io/reference/metrics#recommended-enabling-certificates-for-production-disabled-by-default

We will need to add more options to the metrics config api object to reference the certicates for metrics server configs.
