          Description

          This jira makes protocol buffers protocol changes required for HDFS-2832. HDFS-2832 will have the following subtasks: protocol buffer changes, protocol changes, followed by jiras for implementation changes.

            Patch makes the following changes protocol buffers:

            1. Registration request can send list of storages each with state and stroage ID.
            2. Heartbeat request is changed to send utilization per storage.
            3. Block report request is changed to send report per storage.
            4. Block received and deleted list is sent per storage.

            The change is limited to protocol buffers and translators alone. The rest of the implementation remains the same with only one storage per datanode.

            I think we should also modify BlockReceivedAndDeletedRequestProto using newly defined StorageReceivedDeletedBlocksProto.

            Minor:

            1. In DatanodeStorageProto I will recommend to define optional field after the required field just to follow a convention.
            2. In HeartbeatRequestProto, please rename report to reports because this is a repeated field.

            This is only protocol layer change. The existing tests cover this. I committed the patch.
