In Spring Cloud Sleuth, we instrument async-related components so that the tracing information is passed between threads.
You can disable this behavior by setting the value of `spring.sleuth.async.enabled` to `false`.
If you annotate your method with `@Async`, we automatically create a new Span with the following characteristics:
If you annotate your method with `@Async`, we automatically modify the existing Span as follows:
* If the method is annotated with `@SpanName`, the value of the annotation is the Span's name.
* If the method is not annotated with `@SpanName`, the Span name is the annotated method name.
* The span is tagged with the method's class name and method name.
Since we're modifying the existing span, if you want to maintain its original name (e.g. a span created by receiving an HTTP request)
you should wrap your `@Async` annotated method with a `@NewSpan` annotation or create a new span manually.
