We are changing the upstream requirements.txt and test-requirements.txt to a combinded global-requirements.txt. Changes the checking script to support this as a possible file as well. This should be a seemless backwards compatible change. While modifying this file, also fix the flake8 style issues. Change-Id: I95ccd6f721a2c7f4e873d1de171d569bae0631e8
