Add compability with OpenTelemetry

**Describe the solution you'd like**
Currently, there's no clear way to export metrics or traces running directly from the program.
Opentelemetry allows `auto instrumentation` with [this python package](https://github.com/open-telemetry/opentelemetry-python-contrib/blob/ebe6d1804bccff184edb379d7780469762c7b854/instrumentation/opentelemetry-instrumentation-kafka-python/src/opentelemetry/instrumentation/kafka/__init__.py). If we use sync `kafka-python` it's possible to export traces by just adding `KafkaInstrumentor().instrument()`, in `Jaeger` this is how they look.


However, this will not work with the current implementation of `aiokafka`

I could start the conversation over there as well, however, I think they won't be able to include `aiokafka` since it -unfortunately- does not exposed metrics
