[QST] How to make python sdk wheel package?

How to make python sdk wheel package?

I've modified and tested beam's python sdks.

I've tried to run command to upload local built wheel package to my local repository like below.
```

$> python setup.py sdist bdist_wheel upload -r local
```

Below files are not included in the package made by me.
```

./apache_beam/coders: coder_impl.cpython-36m-x86_64-linux-gnu.so

```

Please, let me know what is right command to make the wheel package?

Imported from Jira [BEAM-9076](https://issues.apache.org/jira/browse/BEAM-9076). Original Jira may contain additional context.
Reported by: ocworld.

Start with setup.py and the documented Python SDK packaging flow, then compare it with the reported `python setup.py sdist bdist_wheel upload -r local` command. Check how the listed `.so` modules are selected for the wheel; the work is done when the correct command or packaging guidance explains how to include them.
