Extend Python API with a new `model.reshape()` overload

Context

Currently there are multiple ways to reshape model inputs in Python API. They are defined as bindings to C++ code.

A new way to reshape has been suggested - implicit input reshaping with a list of input shapes. An example of new, desired overload/Python API function:

1. model has three inputs: A, B and C
2. model is being reshaped with a list of shapes: model.reshape([[2,2], [1, 3, 224, 244], [10]])
3. the given shapes are assigned to respective inputs: A.shape = [2, 2] B.shape = [1, 3, 244, 244] C.shape = [10]

Python API model binding needs to be extended with a new overload which will add this functionality.

What needs to be done?

1. Add a new overload for model.reshape in model C++ bindings
2. Add tests for the new functionality in the correct test file - test_model.py
3. Submit a PR
4. Wait for review
