ARTEMIS-1025 OutOfDirectMemoryError raised from Netty
It solve the OOM issue while under heavy load while:
- allowing the NettyConnection to perform a (configurable) weak form of
backpressure on unbatched "big" messages
- allowing multiple (concurrent) clients to query the memory usage of the
connection
- allowing batching without involving further copies of the data
- providing detailed memory load informations on OOM errors
