Add Support for QLORA/QA-QLORA weights which are not merged

[orellavie1212]

currently only original LORA is supported as not fused adapter, I hope to be able to add the support for QLORA/QA-LORA support for the adapters, without fusing with the base model.

Hi, I am workig on adding QLora support to Vllm.

The first model to support would probably be timdettmers/qlora-alpaca-13b ( and some other qlora models presented by timdettmers in hugging face).
