Implement RSS Discovery Engine to help find feeds of interest

[silverhook]

The RSS Discovery Engine is a neat little (server-side) script and webUI to crawl any page with an RSS/Atom feed for links to further such pages.

It would be cool if Nextcloud News had such a feature, so one could find and add about relevant feeds already from the app itself.

It is still relatively new, but wanted to post it here for awareness and future reference.

We have the discovery part already, thanks to our feed library.

So the API would need to be extended, to give back a list of feeds when given a URL.

And the UI would need to be able to show a list of some sorts.

Unfortunately nobody has invested much time into the front-end, it's very outdated, using the original angular js

So I'm not very optimistic at the moment

I’m not holding my breath, but leaving out here in case things move forward later on. Thanks for maintaining News, BTW! :)
