### Depends on and blocked by #37784 <= merged

Once the external_executor_id bug is fixed, this will add the feature to adopt abandoned tasks in the ECS Executor. To test, you can launch an ECS Executor environment and run a dag which takes a few minutes. While it is running, kill the scheduler. Before this change, when you restart the scheduler, the existing ECS job will be terminated and rescheduled/restarted. After this change, the running task will be adopted; it will finish and be monitored as if it was launched by this executor/scheduler instance.

Was previously #36803

closes: #35491
