Description of problem:

CertificatePolicy execution in a namespace(s) with a great amount of secrets (8000+ in the observed environment) produces a lot of "Skipping this secret" logs that can clogs storage.

As per documentation, "The certificate policy controller automatically looks for a certificate in a secret in only the tls.crt key", having a lot of messages that states that a secret have been skipped since it does not have a certificate in it can cause a lot of not that useful noise.

Version-Release number of selected component (if applicable):

ACM 2.11

ACM 2.12

How reproducible:

Always reproducible

Steps to Reproduce:

1. Install ACM
2. Create a Policy using policy template "Certificate management expiration"
3. Apply policy to any cluster (local-cluster or managed)
4. Use namespaceSelector.include to include namespace you desire
5. Check logs from pod cert-policy-controller in open-cluster-management-agent-addon namespace

Actual results:

Secret in targeted namespaces are checked and if dose not contains tls.crt in it they are skipped and produce an entry like "Skipping this secret" in pod cert-policy-controller-xyz

Expected results:

Messages like "Skipping this secret" are expected but if there are many secrets, logs are putting storage to a risk.
