[AIRFLOW-1059] Reset orphaned tasks in batch for scheduler
The current implementation resets state for tasks
1 dagrun at a time. We
should be able to do this in larger batches, which
will improve
scheduler startup time.
Closes #2205 from saguziel/aguziel-reset-state

> Key: AIRFLOW-1059
> URL: https://issues.apache.org/jira/browse/AIRFLOW-1059
> Project: Apache Airflow
> Issue Type: Improvement
> Reporter: Alex Guziel

> Fix For: 1.9.0

>
> Scheduler startup is very slow due to resetting state making a query for each dag run. We should be able to do this in a constant number of queries which will increase scheduler startup time significantly.
