Provide a way to inject baggage and sentry-trace headers to a request

[OrkhanAlikhanov]

Problem Statement

I have a CLI that makes request to our backend, and wanted to have distributed tracing setup. LLM suggested to use:

// Inject Sentry tracing headers
sentry.TraceRequest(tx.Context(), req)

But apparently such method does not exist. The closest thing I found was from otel package:

sentryotel.NewSentryPropagator().Inject(req.Context(), propagation.HeaderCarrier(req.Header))

Which I don't think will work as I don't have otel setup.

Solution Brainstorm

Add something like sentry.TraceRequest(tx.Context(), req) or sentry.GetTraceHeaders(tx.Context()) methods

Nevermind, seems like baggage is otel specific and sentry backend can work with only sentry-trace header

Hey @OrkhanAlikhanov depending on what framework you're using, trace propagation should already be configured out of the box (see example on fiber here). Currently we don't support automatic trace & baggage injection for outgoing requests currently, but will be looking to add it in the next version, see #876 for more info.
