Azure OpenAI Assistants API Support

[potofo]

We propose supporting Azure OpenAI Assistants API for future multimodal features.

Reason

1. Multimodal LLM cannot cover all office documents
   I want to use Code Interpreter to analyze Office documents
2. APIs must be available in a confidentiality-controlled closed cloud environment
   I want to use it without going through the Internet.
3. Meeting the demands of advanced AI agents
   I want results through sustained interaction, not simple chat.
4. Increased correct answer rate
   Hopes that the AI ​​agent function will enable CoVE (Chain-of-Verification)
