Verify model compatibility if OPENAI_FUNCTIONS is set

[Pwuts]

Background

Not all models support the OpenAI Functions API. It would be nice if we can assume that we can use functions if config.openai_functions is set to True.

Changes

Add a validator to the Config which checks if smart_llm supports the Functions API in case openai_functions is enabled.

If these two settings have incompatible values, it throws an error:

I also had to make a few changes to mitigate circular import errors.
