Delete old container image

As customers apply some patches, the container image size inside the registry grows.

Also, in the air-gap environment, the downloaded container image storage directory will also be large.

I want you to implement a mechanism to delete these images.

* When I asked IBM support, I was advised to run the oc adm prune command with the "--keep-younger-than = <duration>" option.

However, I think that while this method can delete the old container image, it may also delete the container image "actually" used by the cluster.

    Hi, Can you provide more details on why the command support gave you would delete the actual container image being used? Feel free to respond here or to my email
