Dedicated service monitors for core platform monitoring

With this release, the dedicated service monitors feature for core platform monitoring has been removed. You can no longer enable this feature in the `cluster-monitoring-config` config map object in the `openshift-monitoring` namespace. To replace this feature, Prometheus functionality has been improved to ensure that alerts and time aggregations are accurate. This improved functionality is active by default and makes the dedicated service monitors feature obsolete.
