Support for Model load - General issues with Model loading

[JimClarke5]

1. Is there a way to expose the TF C++ file tensorflow/c/checkpoint_reader.cc (class CheckpointReader) to the Java framework? We need this to restore weights and variables from checkpoints and saved models. (@rnett @karllessard @Craigacp). TF Python calls out to this C++ class for this functionality.

Can you use Session.load? It's not the same but it's somewhat close.

I will have to investigate it.
