Unified BulkInference for TFX Pipeline

[ConfuzedCoder]

TFX is framework neutral and can be used with other non-TF ML frameworks but the current version of the bulkInference only supports the Tensorflow model, which limits the ability of TFX. I would like to enhance the buikInference so that it can support many other non-TF frameworks like PyTorch and Xgboost.

Great idea. @tandelDipak do you have a suggestion for the component API?

It's just a thought right now, I don't have anything concrete, I will start working on it, and then we can have some discussion.
