**What you expected to happen**:

All providers should be installed

**How to reproduce it**:

```
./breeze --production-image --python 3.6
```

Then:

```
./breeze --production-image --python 3.6 shell bash
```

then

```
ls -la ~/.local/lib/python3.6/site-packages/airflow/providers/

amazon
google

```
