[provenance] Implement a naive archive multiplexer
- Improve origin layer logs
- Add a missing dependency
- Add a new multiplexed archive type
It queries all the underlying archives and returns the first result found. It a naive implementation but will allow to have a fallback the the swh-storage if some is requested in an outdated swh-graph
