NetflowV9: Kafka server message too large about vflow

[JPercivall]

Rolling back to Kafka version 0.10.2.1 appears to work. Which is in line with the suggested root problem.

Relevant updated docker-compose file:

  kafka:
    image: wurstmeister/kafka:0.10.2.1
    container_name: 'kafka'
    ports:
      - "9092:9092"
    environment:
      KAFKA_ADVERTISED_HOST_NAME: kafka
      KAFKA_ADVERTISED_PORT: 9092
      KAFKA_CREATE_TOPICS: "vflow.netflow9:1:1"
      KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181
      KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181
    depends_on:
      - zookeeper

@JPercivall thanks for looking at this issue. pls create a PR to add MaxRequestSize to the kafka config.

@mehrdadrad, not a problem, thank you for open-sourcing vFlow.

I'm on travel this week but should have a PR up by next week. Will be my first time contributing in GO so please feel free to offer any constructive criticism in the review.
