# Registration request can send list of storages each with state and stroage ID.
# Heartbeat request is changed to send utilization per storage.
# Block report request is changed to send report per storage.
# Block received and deleted list is sent per storage.
The change is limited to protocol buffers and translators alone. The rest of
