Prometheus in 4.7 and 4.8 has the following Prometheus kube metrics in the metric deny list making them unable to reach these metrics. As described in this KCS https://access.redhat.com/solutions/6232571

• --metric-denylist=kube_secret_labels
• --metric-denylist=
  kube_*_created,
  kube_*_metadata_resource_version,
  kube_replicaset_metadata_generation,
  kube_replicaset_status_observed_generation,
  kube_pod_restart_policy,
  kube_pod_init_container_status_terminated,
  kube_pod_init_container_status_running,
  kube_pod_container_status_terminated,
  kube_pod_container_status_running,
  kube_pod_completion_time,
  kube_pod_status_scheduled

Customer is unhappy with this as they use many custom metrics. Customer is asking if we can make it so the Cu can pick and choose which metrics they want to add to the deny list.

Acceptance criteria:

• A solution that enables users to override the already existing (default) denylist.
