For now, accessing /dag_stats can take a relatively long time (e.g. over 20 seconds with less than a million rows on some environment). This patch replaces multiple LEFT OUTER JOINs with INNER JOINs and UNION ALL and improves that process by making it 3-5x faster. Closes apache#1610 from sekikn/AIRFLOW-246
