[AIRFLOW-2231] Fix relativedelta DAG schedule_interval (#3174)
Fixes issues when specifying a DAG with a schedule_interval of type
relativedelta.
> DAG with a relativedelta schedule_interval fails

> Key: AIRFLOW-2231

> Project: Apache Airflow
> Issue Type: Bug
> Components: DAG
> Reporter: Kyle Brooks
> Priority: Major
> Attachments: test_reldel.py
>
>
> The documentation for the DAG class says using
> dateutil.relativedelta.relativedelta as a schedule_interval is supported but
> it fails:
>
> Traceback (most recent call last):
> File "/usr/local/lib/python3.6/site-packages/airflow/models.py", line 285,

>
> It looks like the __init__ function for class DAG assumes the
> schedule_interval is hashable.
