Python: hf sample and generator

[eavanvalkenburg]

Motivation and Context

Adds a parameter to the hugging face text completion class to supply the Pipeline, this allows more customization. Added a sample that shows how to setup quantization for HF models. Not ready to use because of differences in setup and hardware.

Closes: #6374

@eavanvalkenburg, are you still working on this one? Or should we close it out?

[eavanvalkenburg]

@matthewbolanos still want to add this, just has not been a prio, it adds some additional capabilities to the connector as well as a new sample
