> Right now Airflow deletes the task instance when user clear it. We have no way of keeping
track of how many times a task instance gets run either via user or itself. So instead of
deleting the task instance record, we should keep the task instance and make try_number monotonically
increasing for every task instance attempt. max_tries is introduced as an upper bound for
retrying tasks by task itself.
