Review comment:
Kwrags of `url_for` are by default used for endpoint variable arguments
(e.g. `/foo/{var}`), and only unrecognised key-values are appended as a query
string. This works now since (I think) none of Airflow’s endpoints currently
take any arguments, but could introduce subtle bugs in the future. Something
like this is probably better for maintenance down the road.
```python
url = flask.url_for(f"Airflow.{view}")
return f"{url}?{urllib.parse.urlencode(query)}"
```
