This is a breaking change which needs adaptation to the loader.
This:
- drops the no longer used origin keys
- moved the provider, tool and raw_metadata keys to the top-level moved the provider, tool and raw_metadata keys to the top-level.
(origin in the end is still used by the loader when flushing the metadata in the revision...)
The main reason is to cleanup. Took the opportunity since I need a
deployment for D4100 anyways.
