This `api_server.py` file is exact copy version from https://github.com/vllm-project/vllm/blob/v0.6.4.post1/vllm/entrypoints/openai/api_server.py

* The `HUGGING_FACE_HUB_TOKEN` must exist during runtime.

## Documentation about config

* https://github.com/vllm-project/vllm/blob/v0.6.4.post1/vllm/utils.py#L1207-L1221

```shell
"serve,chat,complete",
"facebook/opt-12B",
'--config', 'config.yaml',
'-tp', '2'
```

The yaml is equivalent with argument flag params. Consider passing using flag params that defined here for better documentation:
https://github.com/vllm-project/vllm/blob/v0.6.4.post1/vllm/entrypoints/openai/cli_args.py#L77-L237
