**Apache Airflow version**: 1.10.10, 1.10.11, 1.10.12


**Kubernetes version (if you are using kubernetes)** (use `kubectl version`): 1.15.11, 1.17.7

**Environment**:

- **Cloud provider or hardware configuration**: AKS
- **Others**: Python 3.6, Python 3.7, Python 3.8

Kubernetes executors hangs from time to time on worker pod submission. Pod creation request is timeouting after 15 minutes and scheduler loop continues. I have recreated the problem in several Kubernetes / Python / Airflow version configurations.

How I can configure Airflow to emit logs from imported packages ? I would like to check `urllib3` and `http.client` logs in order to understand the problem. Airflow scheduler logs shows only Airflow codebase logs.
