[Feature Request] Domain per App / Domain mangement

[axelitbue]

When you look to YunoHost or Cloudron, very similary software to CasaOS, your were able to configure a Domain per App, so you can reach the app with app.domain.com.

Actually I use nginx Proxy Manager for that, but Nextcloud as well as Home Assistant has some problems behind a proxy. I solved it and it works, but some minutes passed before it works.
