Remove or pin use of a deprecated python package, google-cloud

This repository contains a setup.py or requirements.txt file that depends on the google-cloud package. This package is deprecated. If you wish to continue to use this package, please pin the version to google-cloud<0.34.0. If you have more time to dedicate to this, I would advise sorting out which sub-packages you actually rely on and depending on them.

For further information please view this package on PyPI, https://pypi.org/project/google-cloud/

Thanks @crwilcox -- will do!

@paxtonfitzpatrick as a temporary fix, can you update setup.py and requirements.txt to specify google-cloud<0.34.0?

Then in a future version we can sort out specific dependencies

tightened to google-cloud>=0.32.0,<0.34.0 (and consequently google-cloud-speech<0.31dev,>=0.30.0) for now. Will sort out in a future version
