- Add a 'devid' storage configuration so that master do not distribute
replicated partitions on storages with same 'devid'.
- Fix race conditions between client-to-storage operations and moved
partitions. Currently, reads succeed because feeding nodes don't delete
anything while the cluster is operational, for performance reasons:
deletion of dropped partitions must be reimplemented in a scalable way.

- Consider insert multiple objects at time in the database, with taking care

- Decentralize primary master tasks as much as possible (consider
distributed lock mechanisms, ...)

- Make storage check if the OID match with it's partitions during a store
- Investigate delta compression for stored data

older revision delta-compressed, in order to save space.
