High-Level programming language bindings for vAccel

[bchalios]

Problem

We want to expose vaccel bindings for high-level programming languages. At the moment, we do expose some Rust bindings. We need to clean up the semantics of these and also add support for, at least, Python

Requirements

1. Cleanup/extend the rust bindings to be more idiomatic.
2. Design respective bindings for Python

We started working on Python vAccel bindings https://github.com/nubificus/python-vaccel

At the moment this wraps the inference operation for TensorFlow models. It also implements all the "management" API, for sessions and resource registration. The API for jetson supported operations will be implemented once we adapt it to the resource registration API.

The API itself exposes Python classes for sessions and TensorFlow models which wrap the underlying C-native objects.
