https://stackoverflow.com/questions/76620276/use-both-b3-and-w3c-trace-formats-in-trace-propagation-between-spring-boot-2-3

b3 to use the concatenated b3: {TraceId}-{SpanId}-{SamplingState}-{ParentSpanId} header
b3_multi to use separate headers such as X-B3-SpanId and X-B3-TraceId
w3c to use the traceparent header
