Data retention settings for package registry

[fuero]

Feature Description

The package registry feature should offer settings for data retention for package versions:

• How long versions are kept,
• how many versions are kept,
• globally, per organization, per repo.

The goal is to allow to conserve space without having to manually delete packages.

If that's already possible, I've missed it in the docs - so please point it out to me :-)

And there should be an option using e.g. Regex or a semver parser to semantically select version to retain e.g. only last 5 prereleases
