Proper way to manage media repository size

[ryester19]

While we wait for #2155 to be implemented, is there a proper and/or robust way to purge the media repository by age and category? For example, I want to purge the repository from everything that's over a week old, while also keeping all avatars

The only simple way I've found so far was to empty the mediaapi_media_repository and mediaapi_thumbnail tables, and delete everything in the uploads folder. But obviously that purges everything
