RFE: Function calling in OpenAI Frontend

[thehumit]

Hello,
Do you have any plans to support function calling with openai-frontend? This will be crucial feature and make me use triton in production instead of such solutions like text-generation inference? Any recommendations how to implement it or other open-source solutions would be amazing.
