[REQ] Record removed images periodically and easily accessible to operators

What kind of request is this?

Improvement of existing experience

What is your request or suggestion?

Currently, for removed images, Eraser record the removed images in logs and records the total count of removed images as a metric. In the event the pod log is gone, this information is gone as well. To make it easier for operators to troubleshoot, would be good to consider some other mechanism to record the removed images somewhere in the cluster periodically.

e.g. Record this as part of the status field of an eraser custom resource along with a timestamp. If etcd object size is a concern, then we can consider a configurable field for the maximum number of recorded removed images.

WDYT?
