KAFKA-4710: Interpolate log4j's logging source interpretation to correct loation info of logs written through trait methods Issue: https://issues.apache.org/jira/browse/KAFKA-4710 This PR fixes location information of log4j `LoggingEvent` which is currently given wrongly due to indirect logger method invocation through Logging trait method. By introducing custom `LoggingEvent` which manually traverses stack trace to find a correct location where the logs are originally written, an appender can now obtain the correct location instead of somewhere inside the `Logging.scala`.
