   Create two mid tasks: 
   _check_one_success_ with trigger rule one_success 
   _check_all_done_ with trigger rule all_done
   Then joining like:
   [task1, task2, ..., taskN] >> check_one_success >> task_with_trigger_rule_at_least_one_success
   [task1, task2, ..., taskN] >> check_all_done >> task_with_trigger_rule_at_least_one_success
