RSS/Atom feeds for each list

It would be great for HK to provide RSS/Atom feeds for all the lists. Private lists would need to handle authentication somehow, but public ones should be able to just update the feed everytime there is a post.

If you wanted to get fancy, perhaps have 2 feeds (one with just subject and a short bit of information and link to the archive, and one with the full post).

We have had this request in Fedora Infrastructure for over 7 years now, would be great it we could make this happen. https://pagure.io/fedora-infrastructure/issue/1002
