class_docstr: Contains Kubernetes Airflow Worker configuration logic.
  
  Represents a kubernetes pod and manages execution of a single pod.
  Any configuration that is container specific gets applied to
  the first container in the list of containers.
  
  :param pod: The fully specified pod. Mutually exclusive with `pod_template_file`
  :param pod_template_file: Path to YAML file. Mutually exclusive with `pod`
  :param extract_xcom: Whether to bring up a container for xcom
