 Review comment:
   Yeah, this should be a config variable at the least.
   
   Also it would be good if 
https://github.com/apache/airflow/blob/df35957fd4bab86ca6d2c923899569fb23139f56/airflow/config_templates/default_airflow.cfg#L782-L787
 applied here (if it doesn't already?) so that this can be set globally for all 
Kube API calls form airflow.
