Add 'max_consecutive_failed_dag_runs' to DAG schema

In the DAG schema, 'max_consecutive_failed_dag_runs' has been added. This attribute determines the threshold for how many consecutive failures will result in the DAG being paused. This will improve error handling, ensuring DAGs are paused promptly if they are consistently failing.
