[FR] Hardlinking capability for sonarr and radarr

[eliottness]

Is your feature request related to a problem? Please describe.
Radarr and Sonarr refuse to hardlink because the downloads and the media volumes are not one and the same. I can't juste ask for a move because I want to be able to seed the torrents I download.

Describe the solution you'd like
The only way to do that is to fuse the downloads, movies, and tv storage subpaths and mounts in the deployment created

My workaround is (only for hostpath volumes) is to put the media folder under the downloads folders so the mounts are still working for jellyfin and make sure sonarr/radarr don't look for the /movies and /tv mounts but at the /downloads/tv and /downloads/movies so hardlink works in the container;
