------------------------------------------------
The patch had a mistake. Did not assign the headerMsgBuf.
Coming to have a new BBPool - so having a smaller sized BBpool where the max
size of elements is equal to headerSize should be created. Not sure whether we
need such a pool for this purpose.
> Use ByteBufferPool for the header and message during Rpc response

> With ByteBufferPool in place we could avoid the byte[] creation in
> RpcServer#createHeaderAndMessageBytes and try using the Buffer from the pool
> rather than creating byte[] every time.
