Clean up of the old images from the registry

The deprecated images need cleaning up from the registry, deleting it from the images.yml loses track of the image

As a starting point, we can create a deprecated directory that has the same subfolders modules has, and move all the tags we don't want to sync anymore.

I'd add a deprecated field to the yaml and filter out the ones that have that field in true in the sync, we could even have some cron that deletes them from the registry after a while also.
As a side note: our registry supports deleting old (unused) images automatically.

instead of deprecated as a field, we could create a deprecated list with all the deprecated tags
