Cleanup cookiecutter defaults

Some of the defaults applied by cookiecutter are not applicable to this
repository and were not cleaned up before getting committed. This patch:

 - updates the project setting so that 'git review' will work properly.
 - updates the docs conf so docs will build
 - updates the setup.cfg so that it can be installed properly
