Added MoveNet as an external model reference (#1141)

* add center padding to size matcher

* add test for center padding

* add ensure_float option to inference layer

* reformat resizing and test_resizing

* add MoveNet as an external model inference

* add the movenet to the from_model_paths

* add tests

* add comments to movenet predictor

* add tensorflow_hub to the requirements.txt

* modified default video path

* resolved most of the comments except expanding the predictor

* expanded Predictor.from_model_paths function to include any pre-trained models.

* add test_load_model

* added from_trained_models in class Predictor and modified test_load_model for it.

* modified test_load_model to be more generalized.

* moved pretrained model from Predictor.from_trained_model to Predictor.from_model_paths and added a test for it.

* Fix Predictor.from_model_paths and tests

* Rename load_movenet_model to make_model_movenet

* minor clean-up

* Remove redundant operation

* Replace existing constants with fixtures

* Handle loading movenet models via load_model API

* Clean-up doc strings
