Review Comment:
   We already support that :-) In Quarkus, W3C Trace Context propagation is 
enabled by default: 
   
   https://quarkus.io/guides/opentelemetry-tracing#propagators
   
   IOW, Polaris correlation ID can be considered a simplified alternative to 
OTel context propagation; but the former doesn't preclude the latter. You can 
perfectly combine both techniques together.
   
   Polaris correlation ID has one small advantage though: it is included in 
Polaris events, while OTel context is not. So the only way to crrelate a 
Polaris event with an OTel trace is to first locate the trace using the 
correlation ID from the event.
