Updating constraints. Build id: 209987675

This update in constraints is automatically committed
by the CI 'constraints-push' step based on
HEAD of 'v1-10-test' in 'apache/airflow'
with commit sha f487f2f

All tests passed in this build so we determined we can push the updated constraints.

See https://github.com/apache/airflow/blob/master/README.md#installing-from-pypi for details.

Note! This was manually updated by Jarek Potiuk as
the build failed in one testi transiently and it was
just before the release of 1.10.12.
