    Implements backup using specialised storage nodes and relying on replication · 8e3c7b01

    Replication is also fully reimplemented:
    - It is not done anymore on whole partitions.
    - It runs at lowest priority not to degrades performance for client nodes.
    Schema of MySQL table is changed to optimize storage layout: rows are now
    grouped by age, for good partial replication performance.
    This certainly also speeds up simple loads/stores.
