Autoscaling support in Ray-llm

[Jiaxin Shan]

Just curious does ray-llm fully leverage ray serve autoscaling (https://docs.ray.io/en/latest/serve/autoscaling-guide.html)?
Seems ray serve only support target_num_ongoing_requests_per_replica and max_concurrent_queries , As we know, LLM output varies and these are not good for LLM scenarios. how do you achieve better autoscaling support for LLM?
