Describe the bug

Older versions of the project have logged OTEL tracing information which allowed correlation of logs and tracing. This functionality is lost now.

How can the bug be reproduced

Just use one of the docker-compose based examples from the main branch and from the older alpha tagged versions. The older will log the relevant data. The newer do not (including the version from the main branch).

Relevant log output

The following snippet shows the expected entries (_parent_id (optionally), _span_id and_trace_id)
