adding Dify.ai support for LLM service

[ramishi]

would be good to support dify api to handle all the LLM Ops and RAG.

from: https://docs.dify.ai/

Dify is an open-source large language model (LLM) application development platform. It combines the concepts of Backend-as-a-Service and LLMOps to enable developers to quickly build production-grade generative AI applications. Even non-technical personnel can participate in the definition and data operations of AI applications.

By integrating the key technology stacks required for building LLM applications, including support for hundreds of models, an intuitive Prompt orchestration interface, high-quality RAG engines, and a flexible Agent framework, while providing a set of easy-to-use interfaces and APIs, Dify saves developers a lot of time reinventing the wheel, allowing them to focus on innovation and business needs.
