Monitoring Dashboard for Image Registry

1. Proposed title of this feature request
Monitoring Dashboard for Image Registry

2. What is the nature and description of the request?
The OpenShift Container Platform 4 - Image Registry is exposing a set of metrics which help to understand it's overall health, performance metrics and other details. Many of OpenShift Container Platform 4 - Components have a dashboard today in /monitoring/dashboards within the OpenShift Container Platform 4 - Console.

It's therefore requested to have a similar metrics Dashboard for the OpenShift Container Platform 4 - Image Registry to help customers understand health state over time, performance of the OpenShift Container Platform 4 - Image Registry and potentially identify problem areas or areas where a bottleneck might be possible.

3. Why does the customer need this? (List the business requirements here)
The OpenShift Container Platform 4 - Image Registry is a key element in OpenShift Container Platform 4 and it's therefore required to have proper observability of that component to understand when it's misbehaving and have usage data/metrics over a define time (to troubleshoot potential problems from the past, etc.).

That will also help to understand if OpenShift Container Platform 4 - Image Registry needs to be scaled or other action needs to be taken due to potential growth of the platform.

4. List any affected packages or components.
