[Feature Request]: OpenTelemetry Support

[Kludex]

What would you like to happen?

This is more a question than a feature request.

I was wondering... Why I don't see any OpenTelemetry related issue on Apache Beam? Is it because the runners already provide observability about their jobs?

I'm more interested in the Python side for now, but if there's no reason, would it make sense to create a opentelemetry-instrumentation-apache-beam package?
