Feature request

It seems that if i want to load a base model with an adapter and consume it, i'll have to use the generate route only which allows specifying adapter_id

`curl 127.0.0.1:3000/generate
-X POST
-H 'Content-Type: application/json'
-d '{ "inputs": "Was "The office" the funniest tv series ever?", "parameters": { "max_new_tokens": 200, "adapter_id": "tv_knowledge_id" } }'

but can't use v1/chat/completions

are you planing to support this?

Motivation

Many use v1/chat/completions and train lora adapters for it
