      Description

      As part of HDFS-12090, Datanodes should be able to receive DatanodeCommands in the heartbeat response that instructs it to backup a block.

      This should take the form of two sub commands: PUT_FILE (when the file is <=1 block in size) and MULTIPART_PUT_PART when part of a Multipart Upload (see HDFS-13186).
