We write to Netty channels in an async fashion, but notify listeners via a transport service adapter before we are certain that the channel write succeeded. In particular, the tracer logs are implemented via a transport service adapter and this means that we can write tracer logs before a write was successful and in some cases the write might fail leading to misleading logs. This commit attaches the transport service adapters to channel writes as a listener so that the notification occurs only after a successful write.
