As an OpenShift administrator
I want to see all critical metrics about images/image streams/image pruner on a single dashboard
so that I can know how many images I have

Acceptance Criteria

• List of Prometheus metrics that might be interesting too see on the dashboard
• Explanations for queries – what do they mean, and how to react on them

Notes

How many image streams (maybe broken down by projects), how many image objects, storage to be used on etcd.
