Would [SpanLogsAppender.java](https://github.com/opentracing-contrib/java-spring-cloud/blob/master/instrument-starters/opentracing-spring-cloud-core/src/main/java/io/opentracing/contrib/spring/cloud/log/SpanLogsAppender.java) be a good place to add a configurable Level check before executing the append using the int values of the levels?
