Right now, [as documented](https://docs.spring.io/spring-boot/docs/3.0.0-SNAPSHOT/reference/htmlsingle/#actuator.micrometer-tracing.getting-started) users have to set this in their config to get span id and trace ids in logs: ``` logging.pattern.level=%5p [${spring.application.name:},%X{traceId:-},%X{spanId:-}] ``` Besides that it abuses the logging level pattern, it is not a good developer experience. I would prefer it to be auto-configured in the case a `Tracer` bean is available. Not sure if this is technically feasible. We should additionally introduce a `logging.pattern.correlation` property which can be used.
