Zendesk ticket #3912 has been linked to this issue.
@nfuden According to the linked Zendesk ticket, when you try to set the tracestate
header in a regular stagedTransformation, it gets overridden/reset by the tracer. Before we dive into adding new options to configurations, can you check what's actually happening, and see if there is an option to do this via a transformation. Since we had that discussion about being able to define more transformations in the chain, we might actually have a use-case for it here ....

Is your feature request related to a problem? Please describe.
I want to set tracestate header value based on value of a header created by transformation when trace is initiated by gateway-proxy. Currently envoy only sets empty tracestate when it initiates the trace.
Describe the solution you'd like
An option in tracing provider configuration that would allow that, e.g.:
Describe alternatives you've considered
Using baggage to propagate the header, but it's currently not propagated by upstream services which makes it a non-viable solution. Using a transformation to set the header doesn't work as it's overridden by the tracer.
Additional Context
No such option is currently available in upstream envoy opentelemetry tracer.
