Use NextCloud as Asset storage

Simple request :slight_smile:

As someone who has quite a big gallery on his homepage, it would be awesome to create a connection between Cockpit and a NextCloud instance.
As a photographer, my photos are all stored in my NextCloud already, so it would be super nice if I could just link to a shared folder which than becomes available in my assets instead of having to upload the photos twice.

That’s it already. Cheers.
