This is a vLLM general plugin for dynamically discovered LoRA adapters from a local directory.
To use, set VLLM_PLUGIN_LORA_CACHE_DIR to a local directory. When vLLM receives a request
for a LoRA adapter foobar it doesn't currently recognize, it will look in that local directory
for a subdirectory foobar containing a LoRA adapter. If such an adapter exists, it will
load that adapter, and then service the request as normal. That adapter will then be available
for future requests as normal.
HF_TOKEN must be set for the tests to run.
