[Feature Request] Keep last n tagged images with a specific tagname

[Erates]

It would be a nice feature where we can configure the action in such a way, that it deletes all tags according to the tag wildcard and are older than x amount of days.

Agreed. Now that some CI tests are in place I was planning to add a by date option. It definitely makes sense on the --tags mode. Are you wanting it on the --keep-n-tagged option also?

[rohanmars]

I've been thinking of using these additional scope filters and options:

     delete-untagged - default 
     delete-tags/tags
     keep-n-tagged
     keep-n-untagged
     exclude-tags
     
     # scope filters
     and-older-than
     and-downloads-less-than (default 5000 for public repo)
     and-contains-labels (docker image labels - need to figure out syntax for matching
     
     # additional actions
     delete-partial-manifests (default false)
     delete-ghost-manfests (default true)
     delete-ghost-referrers-tags (default true)

I've implemented a older-than option in 2b3cd04, it takes precedent and can be applied to all the delete and keep options. It effectively only include in scope those images that are "older than" that value.

I've released v1.0.8/v1 ff99a6e with this feature, so closing this issue.

Thanks for your feedback/suggestion.
