docs: Add detailed docstrings to API models and update OpenAPI spec (#2889)
This PR focuses on improving the developer experience by adding
comprehensive docstrings to the API data models across the Llama Stack.
These docstrings provide detailed explanations for each model and its
fields, making the API easier to understand and use.

**Key changes:**
- **Added Docstrings:** Added reST formatted docstrings to Pydantic
models in the `llama_stack/apis/` directory. This includes models for:
  - Agents (`agents.py`)
  - Benchmarks (`benchmarks.py`)
  - Datasets (`datasets.py`)
  - Inference (`inference.py`)
  - And many other API modules.
- **OpenAPI Spec Update:** Regenerated the OpenAPI specification
(`docs/_static/llama-stack-spec.yaml` and
`docs/_static/llama-stack-spec.html`) to include the new docstrings.
This will be reflected in the API documentation, providing richer
information to users.

**Impact:**
- Developers using the Llama Stack API will have a better understanding
of the data structures.
- The auto-generated API documentation is now more informative.

fix: finish conversion to StrEnum (#2514)
# What does this PR do?

We still had a few enum declared to behave like string as well as enum.
Let's use StrEnum for those.

chore: remove nested imports (#2515)
# What does this PR do?

* Given that our API packages use "import *" in `__init.py__` we don't
need to do `from llama_stack.apis.models.models` but simply from
llama_stack.apis.models. The decision to use `import *` is debatable and
should probably be revisited at one point.

* Remove unneeded Ruff F401 rule
* Consolidate Ruff F403 rule in the pyprojectfrom
llama_stack.apis.models.models

chore: enable pyupgrade fixes (#1806)
# What does this PR do?

The goal of this PR is code base modernization.

Schema reflection code needed a minor adjustment to handle UnionTypes
and collections.abc.AsyncIterator. (Both are preferred for latest Python
releases.)

Note to reviewers: almost all changes here are automatically generated
by pyupgrade. Some additional unused imports were cleaned up. The only
change worth of note can be found under `docs/openapi_generator` and
`llama_stack/strong_typing/schema.py` where reflection code was updated
to deal with "newer" types.

feat(api): don't return a payload on file delete (#1640)
# What does this PR do?

This is to stay consistent with other APIs.

This change registers files in API, even though there are still no
providers. Removing tests that require a provider existing for a merged
API to enable it in API layer.

fix: return 4xx for non-existent resources in GET requests (#1635)
# What does this PR do?

- Removed Optional return types for GET methods
- Raised ValueError when requested resource is not found
- Ensures proper 4xx response for missing resources
- Updated the API generator to check for wrong signatures

```
$ uv run --with ".[dev]" ./docs/openapi_generator/run_openapi_generator.sh
Validating API method return types...

API Method Return Type Validation Errors:

Method ScoringFunctions.get_scoring_function returns Optional type

Closes: https://github.com/meta-llama/llama-stack/issues/1630

Run the server then:

```
curl http://127.0.0.1:8321/v1/models/foo     
{"detail":"Invalid value: Model 'foo' not found"}%  
```

Server log:

```

feat: adding endpoints for files and uploads (#1070)
Summary:
Adds spec definitions for file uploads operations.

This API focuses around two high level operations:
* Initiating and managing upload session
* Accessing uploaded file information

Usage examples:

To start a file upload session:
```
curl -X POST https://localhost:8321/v1/files \
-d '{
   "key": "image123.jpg',
   "bucket": "images",
   "mime_type": "image/jpg",
   "size": 12345
}'

# Returns
{
  “id”: <session_id>
  “url”: “https://localhost:8321/v1/files/session:<session_id>”,
  "offset": 0,
  "size": 12345
}

```

To upload file content to an existing session
```
curl -i -X POST "https://localhost:8321/v1/files/session:<session_id> \
  --data-binary @<path_to_local_file>

# Returns
{
  "key": "image123.jpg",
  "bucket": "images",
  "mime_type": "image/jpg",
  "bytes": 12345,
  "created_at": 1737492240
}

# Implementing on server side (Flask example for simplicity):
@app.route('/uploads/{upload_id}', methods=['POST'])
def upload_content_to_session(upload_id):
    try:
        # Get the binary file data from the request body
        file_data = request.data

        # Save the file to disk
        save_path = f"./uploads/{upload_id}"
        with open(save_path, 'wb') as f:
            f.write(file_data)
        return {__uploaded_file_json__}, 200
    except Exception as e:
        return 500

```

To read information about an existing upload session
```
curl -i -X GET "https://localhost:8321/v1/files/session:<session_id>

# Returns
{
  “id”: <session_id>
  “url”: “https://localhost:8321/v1/files/session:<session_id>”,
  "offset": 1024,
  "size": 12345
}
```

To list buckets
```
GET /files

# Returns
{
  "data": [
     {"name": "bucket1"},
     {"name": "bucket2"},
   ]
}
```

To list all files in a bucket
```
GET /files/{bucket}

# Returns
{
  "data": [
    {
      "key": "shiba.jpg",
      "bucket": "dogs",
      "mime_type": "image/jpg",
      "bytes": 82334,
      "created_at": 1737492240,
    },
    {
      "key": "persian_cat.jpg",
      "mime_type": "image/jpg",
      "bucket": "cats",
      "bytes": 39924,
      "created_at": 1727493440,
    },
  ]
}
```

To get specific file info
```
GET /files/{bucket}/{key}

{
  "key": "shiba.jpg",
  "bucket": "dogs",
  "mime_type": "image/jpg",
  "bytes": 82334,
  "created_at": 1737492240,
}

```

To delete specific file
```
DELETE /files/{bucket}/{key}

{
  "key": "shiba.jpg",
  "bucket": "dogs",
  "mime_type": "image/jpg",
  "bytes": 82334,
  "created_at": 1737492240,
}

```
