Version-Release number of selected component (if applicable):
4.9.33

How reproducible:
Enable mTLS with a CRL

Actual results:
CRL is not download when expired
Clients get "SSL client certificate not trusted" errors while accessing resources

Expected results:
ingress-operator triggers CRL download when approaching expiration date so that the configmap is updated without manual action
