Make the send / receive socket buffer size configurable in server.
KafkaConfig.scala already has the following existing variables to support send / receive buffer:
socketSendBuffer
socketReceiveBuffer
The patch attached to this ticket will read the following existing settings in <kafka>/config/server.properties and set the corresponding socket buffers
. . .
The send buffer (SO_SNDBUF) used by the socket server
socket.send.buffer=1048576
The receive buffer (SO_RCVBUF) used by the socket server
socket.receive.buffer=1048576
