OTEL provider for Airflow release 1.0.0
Initial release, which covers the following:
- OTEL hook for creating trace, metrics, and logs within the DAG file, emitting telemetry data in OTEL format
- event listener to instrument DAG runs and task instances
Hooks and event listener will be enabled depending on Airflow version compatible (having OTEL tracing), and also for older version of Airflow that does not.
