We need to document how to configure audit logs in Prometheus. 4.10 and above.

Users can enable audit logs in the Prometheus Adapter by applying the following config-map:

apiVersion: v1
kind: ConfigMap
metadata:
name: cluster-monitoring-config
namespace: openshift-monitoring
data:
config.yaml: |
  k8sPrometheusAdapter:}}}}
    auditLevel: Metadata  ### Request, RequestResponse (default None)

The CMO picks up the change and (re)deploys prometheus-adapter with appropriate -audit flags.

Probably should also include a link to the api server audit log docs: https://docs.openshift.com/container-platform/4.8/security/audit-log-view.html
