chore: OpenAI compatibility for Milvus (#2470)

# What does this PR do?
Closes https://github.com/meta-llama/llama-stack/issues/2461



## Test Plan
Tested with the `ollama` distriubtion template and updated the vector_io
provider to:
```yaml
vector_io:
- provider_id: milvus
  provider_type: inline::milvus
  config:
    db_path: ${env.SQLITE_STORE_DIR:=~/.llama/distributions/ollama}/milvus_store.db
    kvstore:
      type: sqlite
      db_name: milvus_registry.db
```

Ran the stack
```bash
llama stack run ./llama_stack/templates/ollama/run.yaml --image-type venv --env OLLAMA_URL="http://0.0.0.0:11434"
```

Ran the tests:
```
pytest -sv --stack-config=http://localhost:8321 tests/integration/vector_io/test_openai_vector_stores.py  --embedding-model all-MiniLM-L6-v2
```
Output passed.
