#4457 Python: clean up grpc api, Python client API and make installable python package (#4456)

* gRPC: Make names more consistent

* gRPC: clean up case info and improve Python API for cases

* gRPC: much more object oriented Python interface

* Python: Make a proper pip-installable package

* Update rips Python package to auto generate setup.py with version number

* Python: add setup.py to gitignore

* Python: Update Python RIPS interface

* gRPC: Remove example client from cmake file and unit test

* gRPC: Fix up unit test after merge and hide warnings
