Add the huggingface token parameter, and modify the file path in llama.cpp repo

[melodyliu1986]

I want to use the mistralai/Mistral-7B-Instruct-v0.2 model, and found there are no gguf files in HuggingFace, then I decided to use the ./convert_models functions to convert the model. I found there are some issues exist:

1. 401 Client Error

huggingface_hub.utils._errors.GatedRepoError: 401 Client Error. (Request ID: Root=1-66b1862a-1bc229376e7f3f4020a3c951;60195d59-03d1-4f26-b3ce-d3b04c2fe2b4)
Cannot access gated repo for url https://huggingface.co/mistralai/Mistral-7B-Instruct-v0.2/resolve/36d7e540e651b68dac59394d9c3381651df7fb01/.gitattributes

So I added the optional HF_TOKEN=<YOUR_HF_TOKEN_ID> parameter in the code. If the users want to download the public model, there is no token needed; If the users want to download the private model, they need to use the huggingface token;
Impacted files: README.md, download_huggingface.py, run.sh

2. No convert.py and quantize files under llama.cpp

python: can't open file '/opt/app-root/src/converter/llama.cpp/convert.py': [Errno 2] No such file or directory
run.sh: line 23: llama.cpp/quantize: No such file or directory

If we go to https://github.com/ggerganov/llama.cpp.git, we can find the convert.py has been deprecated and moved to examples/convert_legacy_llama.py. I am not sure if I should just keep the line "python llama.cpp/convert-hf-to-gguf.py /opt/app-root/src/converter/converted_models/$hf_model_url", I just replace the convert.py with the correct path. also for llama.cpp/quantize

Impacted file: run.sh

3. No image name was specified in the README.md

So I added "converter" in the "podman run" command.

4. Modified the huggingface token parameter to UI web.
   Impacted file: ui.py

Here is my testing after the modification:

$ podman run -it --rm -v models:/converter/converted_models -e HF_MODEL_URL=mistralai/Mistral-7B-Instruct-v0.2 -e HF_TOKEN=*** -e QUANTIZATION=Q4_K_M -e KEEP_ORIGINAL_MODEL="False" localhost/converter

I made some mistakes in the previous PR #741, so I closed it. Is there anyway to delete 741?

I made changes according to your comments, please review it again.
