Take full advantage of object storages #54674
Description
When we are using an object store and not using server side encryption, Nextcloud clients (web/desktop/...) should do as many operation as possible directly on the object store without relying on Nextcloud. This is possible thanks to pre-signed links which allow to do some operation for a certain amount of time.
Must have (P0/S)
