GWELLS: Image Registry using more than allotted space

[LolandaE]

Describe the task
Clean up unnecessary images and tags in the ImageStreams asap.

Issue:
Platform team has indicated that our "Your namespace d1b5d2-dev is using more than 50Gi in the image registry on the Silver cluster of the Private Cloud OpenShift platform. When the image registry becomes full, none of the product teams working in the Silver cluster will be able to push images to it which will have a negative impact on their ability to run development activities for their apps. "

Additional context
There are likely images not being used anymore. Folders with images are taking up space. Currently no automation to remove them (e.g. CRON job)
