multi-lora documentation fix

[ElefHead]

Minor fixes to the documentation for open-ai compatible server.

[simon-mo]

Hi @ElefHead, thank you for your PR, however, at the beginning of the api_server.py, we noted:

vllm/vllm/entrypoints/api_server.py

Lines 1 to 5 in 71bcaf9

	"""
	NOTE: This API server is used only for demonstrating usage of AsyncEngine and simple performance benchmarks.
	It is not intended for production use. For production use, we recommend using our OpenAI compatible server.
	We are also not going to accept PRs modifying this file, please change `vllm/entrypoints/openai/api_server.py` instead.
	"""

Please revert the change in api_server, we are happy to accept the documentation change!

Thanks! Was just confused between using vllm.entrypoints.openai.api_server and vllm.entrypoints.api_server

Hello, why only support s-lora in openai api?

Any plans to support it in vllm.entrypoints.api_server？Thank you. @ElefHead

I mentioned it here:
#3174

Seems the implementation is not completed. There is no lora information in the generate server api.

The generate server API is not recommended for production usage. We kept it not to break existing usage. The OpenAI server provide a superset of functionality and uses the same engine under the hood.
