@kaxil while I think the functionality could be baked into trigger rules, I
can see two problems with that:
1. How would the API look? Today you have something like
```python
my_task = PythonOperator(
task_id='my_task',
trigger_rule='all_success'
)
```
Something like `trigger_rule={"state": "all_success", "include_date":
...}` – ?
I think the interface suggested in this pull request fits better with
the existing `start_date` and `end_date` parameters.
2. The `include_date` and `exclude_date` parameters match on the DAG run
(specifically, the execution date) and are not tied to the task dependencies
(unlike trigger rules).
