Azure OpenAI Support

[KylePancamo]

Hey there.

I've noticed the langchain version being used is a bit old, and doesn't support azure open ai's properties for using it. Will there be an update in the near future for this support?

Support for arbitrary OpenAI compatible endpoints would be nice. Make sit really difficult/impossible to try out projects like these with your own enterprise endpoints, or LocalAI
