**Apache Airflow version**: 1.10.10
**Kubernetes version (if you are using kubernetes)** (use `kubectl version`):
`Client Version: version.Info{Major:"1", Minor:"18", GitVersion:"v1.18.6", GitCommit:"dff82dc0de47299ab66c83c626e08b245ab19037", GitTreeState:"clean", BuildDate:"2020-07-15T16:58:53Z", GoVersion:"go1.13.9", Compiler:"gc", Platform:"linux/amd64"}
Server Version: version.Info{Major:"1", Minor:"17+", GitVersion:"v1.17.6-eks-4e7f64", GitCommit:"4e7f642f9f4cbb3c39a4fc6ee84fe341a8ade94c", GitTreeState:"clean", BuildDate:"2020-06-11T13:55:35Z", GoVersion:"go1.13.9", Compiler:"gc", Platform:"linux/amd64"}
`
**Environment**:
- **Install Tool**:
`helm install stable/airflow --namespace "airflow" --generate-name`
**What happened**:
Using the examples from here & running `python` or `airflow list_dags` would result in:
```text
[2020-07-29 00:14:17,178] {dagbag.py:239} ERROR - Failed to import: /opt/airflow/dags/example_bash_operator.py
Traceback (most recent call last):
File "/home/airflow/.local/lib/python3.6/site-packages/airflow/models/dagbag.py", line 236, in process_file
m = imp.load_source(mod_name, filepath)
File "/usr/local/lib/python3.6/imp.py", line 172, in load_source
module = _load(spec)
File "<frozen importlib._bootstrap>", line 684, in _load

File "<frozen importlib._bootstrap_external>", line 678, in exec_module
File "<frozen importlib._bootstrap>", line 219, in _call_with_frames_removed
File "/opt/airflow/dags/example_bash_operator.py", line 24, in <module>
from airflow.operators.bash import BashOperator
ModuleNotFoundError: No module named 'airflow.operators.bash'
'```
Worked when I switched to the deprecated way of importing it:
```diff
-from airflow.operators.bash import BashOperator
+from airflow.operators import BashOperator
```
**What you expected to happen**:
Module to properly load and not require me to use the deprecated import.
**How to reproduce it**:
```shell
# Repo with the examples
helm install stable/airflow --namespace "airflow" --generate-name
```
```shell
#Attempt to list dags
kubectl exec --namespace airflow -it $SCHEDULER_NAME -- /bin/bash
airflow list_dags
```

I was reading the master branch examples and it looks like there was a major refactor of module imports.
Obviously once I switched the branch over to the current tag I'm using the examples switched to the prior way and I was able to use those examples correctly.
