Support X-Correlation-ID in header

[PSeitz]

Add support for X-Correlation-ID in the header.

The X-Correlation-ID is an id that gets passed by a client and is getting printed in the logs.
This allows end to end tracing of requests across systems.

could be interesting to use trace propagation with https://github.com/tokio-rs/tracing-opentelemetry

So we do have trace propagation using opentelemetry. I think Pascal means (I am not sure) putting the trace in logs, so that we can look at logs, get a request id, and check at the trace.

I wrote code to extract the trace id a few years ago. I ended up trashing it assuming we would never use it. (Also the code to extract it was pretty ugly)
