New trace is created in presence of x-cloud-trace-context

[sk-]

• This only affects the JavaScript OpenTelemetry library
• This may affect other libraries, but I would like to get opinions here first

I'm trying to trace Firebase Cloud Functions, and so far the http and https plugins are generating the spans, however, a new trace id is created instead of reusing the one provided in the context.

The request I receive has the header x-cloud-trace-context. Below an example value I got:

x-cloud-trace-context: 97be22054737c8368a6173b7b5b3ac12/9492297704906512426;o=1

One of the issues this has is that the logs generated in my app have the trace 97be22054737c8368a6173b7b5b3ac12, so that they are not attached the trace.

Is it something that I'm missing?

OpenTelemetry does not support vendor-specific trace headers. Maybe @mayurkale22 knows if there are plans to create a propagator for this in the future?

GoogleCloudPlatform/opentelemetry-operations-js#26 this is the original issue. AFAIK no one is working on the issue, feel free to comment on original issue if you like to work on it.
