chore!: remove model mgmt from CLI for Hugging Face CLI (#3700)

Browse source 
This change removes the `llama model` and `llama download` subcommands
from the CLI, replacing them with recommendations to use the Hugging
Face CLI instead.

Rationale for this change:
- The model management functionality was largely duplicating what
Hugging Face CLI already provides, leading to unnecessary maintenance
overhead (except the download source from Meta?)
- Maintaining our own implementation required fixing bugs and keeping up
with changes in model repositories and download mechanisms
- The Hugging Face CLI is more mature, widely adopted, and better
maintained
- This allows us to focus on the core Llama Stack functionality rather
than reimplementing model management tools

Changes made:
- Removed all model-related CLI commands and their implementations
- Updated documentation to recommend using `huggingface-cli` for model
downloads
- Removed Meta-specific download logic and statements
- Simplified the CLI to focus solely on stack management operations

Users should now use:
- `huggingface-cli download` for downloading models
- `huggingface-cli scan-cache` for listing downloaded models

This is a breaking change as it removes previously available CLI
commands.

To download models, you can use the llama download command.
#### Downloading from [Meta](https://llama.meta.com/llama-downloads/)
Here is an example download command to get the 3B-Instruct/11B-Vision-Instruct model. You will need META_URL which can be obtained from [here](https://llama.meta.com/docs/getting_the_models/meta/). Note: You need to quote the META_URL
Download the required checkpoints using the following commands:
First, install the Hugging Face CLI:
```bash
# download the 8B model, this can be run on a single GPU
llama download --source meta --model-id Llama3.2-3B-Instruct --meta-url 'META_URL'
# you can also get the 70B model, this will require 8 GPUs however
llama download --source meta --model-id Llama3.2-11B-Vision-Instruct --meta-url 'META_URL'
# llama-agents have safety enabled by default. For this, you will need
# safety models -- Llama-Guard and Prompt-Guard
llama download --source meta --model-id Prompt-Guard-86M --meta-url 'META_URL'
llama download --source meta --model-id Llama-Guard-3-1B --meta-url 'META_URL'
pip install huggingface_hub[cli]
```
#### Downloading from [Hugging Face](https://huggingface.co/meta-llama)
### Download models from Hugging Face
Essentially, the same commands above work, just replace `--source meta` with `--source huggingface`.
You can download models using the `huggingface-cli download` command. Here are some examples:
```bash
llama download --source huggingface --model-id Llama3.1-8B-Instruct --hf-token <HF_TOKEN>
# Download Llama 3.2 3B Instruct model
huggingface-cli download meta-llama/Llama-3.2-3B-Instruct --local-dir ~/.llama/Llama-3.2-3B-Instruct
llama download --source huggingface --model-id Llama3.1-70B-Instruct --hf-token <HF_TOKEN>
# Download Llama 3.2 1B Instruct model
huggingface-cli download meta-llama/Llama-3.2-1B-Instruct --local-dir ~/.llama/Llama-3.2-1B-Instruct
llama download --source huggingface --model-id Llama-Guard-3-1B --ignore-patterns *original*
llama download --source huggingface --model-id Prompt-Guard-86M --ignore-patterns *original*
```
**Important:** Set your environment variable `HF_TOKEN` or pass in `--hf-token` to the command to validate your access. You can find your token at [https://huggingface.co/settings/tokens](https://huggingface.co/settings/tokens).
```{tip}
Default for `llama download` is to run with `--ignore-patterns *.safetensors` since we use the `.pth` files in the `original` folder. For Llama Guard and Prompt Guard, however, we need safetensors. Hence, please run with `--ignore-patterns original` so that safetensors are downloaded and `.pth` files are ignored.
# Download Llama Guard 3 1B model
huggingface-cli download meta-llama/Llama-Guard-3-1B --local-dir ~/.llama/Llama-Guard-3-1B
# Download Prompt Guard model
huggingface-cli download meta-llama/Prompt-Guard-86M --local-dir ~/.llama/Prompt-Guard-86M
```
**Important:** You need to authenticate with Hugging Face to download models. You can do this by:
1. Getting your token from [https://huggingface.co/settings/tokens](https://huggingface.co/settings/tokens)
2. Running `huggingface-cli login` and entering your token

## Understand the models
The `llama model` command helps you explore the model’s interface.
1. `download`: Download the model from different sources. (meta, huggingface)
2. `list`: Lists all the models available for download with hardware requirements for deploying the models.
3. `prompt-format`: Show llama model message formats.
4. `describe`: Describes all the properties of the model.
### Sample Usage
`llama model <subcommand> <options>`
```
llama model --help
```
```
usage: llama model [-h] {download,list,prompt-format,describe,verify-download,remove} ...
Work with llama models
options:
-h, --help show this help message and exit
model_subcommands:
{download,list,prompt-format,describe,verify-download,remove}
```
### Describe
You can use the describe command to know more about a model:
```
llama model describe -m Llama3.2-3B-Instruct
```
```
