Review comment:
You could also implement this as an annotation / decorator.
Take a look at s3 for example:
- The creation: https://github.com/apache/airflow/blob/master/airflow/providers/amazon/aws/hooks/s3.py#L45-L65
- The call: https://github.com/apache/airflow/blob/master/airflow/providers/amazon/aws/hooks/s3.py#L140
