v2.3.0

Important changes

• Renamed HUGGINGFACE_HUB_CACHE to use HF_HOME. This is done to harmonize environment variables across HF ecosystem. So locations of data moved from /data/models-.... to /data/hub/models-.... on the Docker.

• Prefix caching by default ! To help with long running queries TGI will use prefix caching a reuse pre-existing queries in the kv-cache in order to speed up TTFT. This should be totally transparent for most users, however this has required a instense rewrite of internals and therefore bugs can potentially exist. Also we changed kernels from paged_attention to flashinfer (and flashdecoding as a fallback for some specific models that aren't supported by flashinfer).

• Lots of performance improvements with Marlin and quantization.
