Trace through Cloud Pub/Sub

[davedc]

Is your feature request related to a problem? Please describe.
Trace context is not passed in on publish on a topic. This leads to detached spans created on subscribers.

Describe the solution you'd like
A @opentelemetry/plugin-gcp-pubsub and a GCPPubSubPropagator class to automatically inject and extract Context.

Describe alternatives you've considered
Manually injecting the trace context via Message attributes but no way to extract on the other side.

Additional context
Am expecting something similar to this googleapis/cloud-trace-nodejs#1076 (comment) without manually having to create spans.

Please kindly point me to the right place if this isn't the correct repo to submit this feature request. Thanks!

Is this solved by googleapis/nodejs-pubsub#1078?

Yes, pubsub node is instrumented directly now 🙂 I'm going to close this

Yes, this ticket can be closed, but love to get some feedback from Google Trace Opentelemetry team about the attributes I am sending and if it matches what the spec had it mind. I think in future releases of google-pubsub improvements can be made :)

I'll take a look at the pubsub PR
