class_docstr: Common implementation for operators, including unmapped and mapped.
  
  This base class is more about sharing implementations, not defining a common
  interface. Unfortunately it's difficult to use this as the common base class
  for typing due to BaseOperator carrying too much historical baggage.
  
  The union type ``from airflow.models.operator import Operator`` is easier
  to use for typing purposes.
