> The new clean up task in the K8 executor queries the DB for all running tasks/dags for each tasks to check for safe labels (tasks and dagid) as they may have needed to be altered for k8 safety.
> For hundereds of tasks finishing, this is a very long process (lots of DB calls and a large loop).
> There's an improvement we can make to to quickly exit the loop if we don't need to check for the label saftly
