[FLINK-1650] Configure Netty (akka) to use Slf4j.
It seems that Netty 3.8.0 used by Akka was using `java.util.logging` for
its internal logging, that's why this entry was without effect:
https://github.com/apache/flink/blob/master/flink-dist/src/main/flink-bin/conf/log4j.properties#L29.
The change sets the Netty logging factory to Slf4j. This means that Netty
is now using Sfl4j. It'll also respect our logging settings
(`org.jboss.netty.channel.DefaultChannelPipeline` to lvl ERROR).
Lets see if the exception now disappears.
