OpenTelemetry AioKafka Instrumentation

This library provides OpenTelemetry instrumentation for the `aiokafka` client, enabling automatic tracing of Kafka producer and consumer operations within `asyncio` applications. As part of the `opentelemetry-python-contrib` project, it currently operates under a beta release schedule (0.x.x series) with frequent updates and bug fixes, aligning with the broader OpenTelemetry Python ecosystem development.
