[AIRFLOW-78] airflow clear leaves dag_runs
Fix a bug in the scheduler where dag runs cleared via CLI would be picked up
without checking max_active_dag_runs first, resulting in too many simultaneous
dag runs.
Dear Airflow Maintainers,
Please accept this PR that addresses the following issues:
- https://issues.apache.org/jira/browse/AIRFLOW-78
Testing Done:
- Expanded the jobs.test_scheduler_verify_max_active_runs test to test if
scheduler respects max_active_dag_runs
Fix a bug in the scheduler where dag runs cleared via CLI would be picked up
without checking max_active_dag_runs first, resulting in too many simultaneous
dag runs.
Closes #1716 from normster/clear_dagrun

> "airflow clear -c -d -s 2016-01-03 dagid" doesn't clear the dagrun, it sets
> it to running instead (apparently since this is often used to re-run jobs).
> However this then breaks max_active_runs=1 (I have to stop the scheduler,
> then airflow clear, psql to delete the dagrun, then start the scheduler).
> This problem was probably seen on an Airflow 1.6.x install.
