Datanode xceiver protocol should allow reuse of a connection

      Description

      Right now each connection into the datanode xceiver only processes one operation.

      In the case that an operation leaves the stream in a well-defined state (eg a client reads to the end of a block successfully) the same connection could be reused for a second operation. This should improve random read performance significantly.
