StageLogging

All Known Implementing Classes:

GraphStageLogicWithLogging, RestartWithBackoffLogic, TimerGraphStageLogicWithLogging
```
public interface StageLogging
```
Simple way to obtain a LoggingAdapter when used together with an Materializer. If used with a different materializer NoLogging will be returned.
Make sure to only access log from GraphStage callbacks (such as pull, push or the async-callback).
Note, abiding to akka.stream.ActorAttributes.logLevels has to be done manually, the logger itself is configured based on the logSource provided to it. Also, the log itself would not know if you're calling it from a "on element" context or not, which is why these decisions have to be handled by the operator itself.
