[FLINK-3151] [runtime] Downgrade to Netty version 4.0.27.Final Netty versions >= 4.0.28.Final contain an improvement by Netty, which slices a Netty buffer instead of doing a memory copy (https://github.com/netty/netty/issues/3704) in the LengthFieldBasedFrameDecoder. In some situations, this interacts badly with our Netty pipeline leading to OutOfMemory error. To reproduce, run batch WordCount with a range partitioner and reasonably large data.
