Use external storage

[Olyno]

Hi 👋🏻
It would be interesting to connect some external storages to Supabase.

From Lio on Discord:

Would it be possible to have a "Bring Your Own S3" for object storage in hosted supabase? I'd love to use the storage features in supabase-js but having to move my CDN over entirely is... not something I'd be looking forward to
