Description

Now that vllm supports llama2 properly, would be awesome to have a peft weight-sharing worker like for regular model serving. The comment at the end of this issue is probably enough to spike one:

Research direction

Start by reviewing FastChat's existing regular model-serving worker and the referenced vLLM issue 182. Determine the required scope for a llama2-compatible PEFT weight-sharing worker and compare it with the current serving design; done means the worker supports the requested multi-worker serving behavior.
