Method for injecting trace parent into curl

[jeeftor]

I wrote my own cli client for Otel and then found this one ... is there a way to inject the trace parent from an exec into the curl headers so I can see the full round trip of my existing tracing with this command?

There's not an easy way to do it right now. I had an old issue for this that I'll work on now that I have a request for it.

The way I've done it so far is with a TRACEPARENT environment variable.

traceparent_file=$(mktemp)
otel-cli span --name "first span in the trace" --tp-carrier $traceparent_file --tp-export --endpoint https://collector
. $traceparent_file
otel-cli exec --endpoint https://collector -- curl -X "traceparent: $TRACEPARENT" https://site.com/file

Ended up just writing my own client

Released 0.4.3 with the injection feature. Sorry the timing didn't work out @jeeftor, and thanks for the bump to get this feature in.
