/**
 * Set the trace and span ID fields of the log entry to the current one.
 * <p>The current trace ID is either the trace ID stored in the Mapped Diagnostic Context (MDC)
 * under the "X-B3-TraceId" key or, if none set, the current trace ID set by
 * {@link #setCurrentTraceId(String)}. The current span ID is retrieved from the MDC
 * under the "X-B3-SpanId" key, if set.
 * <p>The trace ID is set in the log entry in the "projects/[GCP_PROJECT_ID]/traces/[TRACE_ID]"
 * format, in order to be associated to traces by the Google Cloud Console.
 * <p>If an application is running on Google App Engine, the trace ID is also stored in the
 * "appengine.googleapis.com/trace_id" field, in order to enable log correlation on the logs
 * viewer.
