[paul-tharun]

Added google cloud vision as OCR engine.
Implementation is similar to how the AWS TextractOCREngine is implemented

Thanks for your PR, super happy to merge, once I get time reviewing this next week!

1.) Could you maybe add a small test? Something very similar to this would be very helpful. The API itself is mocked, it should be very straight forward.

2.) Could you add the google.cloud.vision dependency to the setup.py: additional_deps and _DEPS ? This will add yet another dependency, but I will have to refactor this anyway.

Thanks again.

Thanks again for your PR.

The code itself looks fine.

3.) Please check the remaining lint, mypy and test -issues:
