[AIRFLOW-1166] Speed up _change_state_for_tis_without_dagrun
_change_state_for_tis_without_dagrun was locking a
significant
amount of tasks uncessarily. This could end up in
a deadlock
in the database due to the time the lock stood.
Closes #2267 from bolkedebruin/fix_deadlock
> _change_state_for_tis_without_dagrun can take very long and end up in
> deadlocks

> Key: AIRFLOW-1166
> URL: https://issues.apache.org/jira/browse/AIRFLOW-1166
> Project: Apache Airflow
> Issue Type: Bug
> Affects Versions: 1.8.1
> Reporter: Bolke de Bruin
> Assignee: Bolke de Bruin
> Labels: scheduler
> Fix For: 1.8.2
>
>
> While testing multi-scheduler setups we've seen some serious delays (>8s,
> with just one dag running) in _change_state_for_tis_without_dagrun. This can
> also result in deadlocks in the db due to the fact the query in
> _change_state_for_tis_without_dagrun is locking a significant amount of task
> instances. This is unnecessary.
