Output scores from LLMChain

[einarbmag]

It would be great to get the score output of the LLM (e.g. using Huggingface models) for use cases like NLU. It doesn't look possible with the current LLM and chain classes as it specifically selects the "text" in the output only. I'm resorting to writing my own classes to allow this, but haven't thought much about how that would integrate with the rest of the framework.
Is it something you have considered?
