What would you like to see in the library?

In order to be spec compliant with the latest stable version of OpenTelemetry semantic conventions, the @google-cloud/pubsub library needs to add the following attribute to its spans: messaging.operation (required). messaging.operation is already included in the span name; it just needs to added to the span attributes as well.

This is a S change that I can submit a PR for; we just need to add these attributes to the create...Span methods in src/telemetry-tracing.ts:

• For publisher spans, messaging.operation will be set to create.
• For subscriber spans, messaging.operation will be set to receive.
