HuggingFace Model Provider[FEAT]

[JINO-ROHIT]

Im raising an early draft PR to ask for feedback as this is only the bare scaffolding and I wanted to clarify couple things. Links #1380

1. Should i implement all the methods from the base class since different providers have done it differently(is there a sample i can refer )
2. are we implementing for the transformer package AutoCausal LM or the hf inference client?

@manthanguptaa would love your guidance here
