More narrow definition of https://github.com/GoogleCloudPlatform/functions-framework/issues/34, the Functions Framework contract should have a specific section around exposing the trace ID of an event-driven function to the user.
Specifically, we can expose:
traceparent
cloudevent.traceparent
See CloudEvent extension for more details: https://github.com/cloudevents/spec/blob/master/extensions/distributed-tracing.md
The older x-cloud-trace-context does not need to be propagated. This is an older value that is replaced by the standard W3C trace context header.
