I notice increasing demand/expectations from user for built-in integration with Distributed tracing.
One such example is Knative where Distributed tracing was integrated from the start.

Some time ago two major parties - OpenCensus and OpenTracing merged to OpenTelemetry and now Tracing API considered mature - https://github.com/open-telemetry/opentelemetry-go.

As a first step towards full Distributed tracing support I propose to integrate Tracing context propagation.

• I suggest to use headers as it is done for example here - https://github.com/knative-sandbox/eventing-rabbitmq/blob/main/cmd/ingress/main.go#L153 to carry context information.
• I suggest to have same header names across all officially supproted RabbitMQ clients.
• I argue that merely providing the header naming suggestion in the official docs will be a great step forward as it sets the ground for future development and solves compatibility issues immediately.

Feedback is much appreciated!
