Describe your environment

Kubernetes python application with autoinstrumentation:

ghcr.io/open-telemetry/opentelemetry-operator/autoinstrumentation-python:0.55b1

What happened?

I have a lot of empty recv span generated by the confluent-kafka python instrumentation

Steps to Reproduce

Instrument a consumer with the confluent-kafka instrumentation

Expected Result

Avoid creating a span when there are no fetched records like the java instrumentation:

Actual Result

not usefull traces are generated with only a recv span
