Substreams can already return the trace_id to the user. Based on how that feature works, add a new feature to allow an additional message to be returned to the consumer.

The operator could configure --common-connect-message: foobar

Then when user connects they could receive an "operator message: foobar". Graph-node could log this information for debugging purposes.
