stream-clone: add a v3 version of the protocol
This new version is less rigid regarding the extract number of files and number

The format stays experimental, but this is an interesting base to build upon.

============================================================================ Pulling from modern to a non-general delta target (and other related checks) ============================================================================ There is various issue that can arise when we update the code with modern storage in mind while working on delta processing. So this file is meant for various scenario that might break in the future or have break in the past.
