Log the error message when git clone fails, not just the return code

[logworthy]

I was trying to run the below command and getting a git error:

cookiecutter(template='https://github.com/drivendata/cookiecutter-data-science')

The current behavior only displays the return code of the git process:

subprocess.CalledProcessError: Command '['git', 'clone', 'https://github.com/drivendata/cookiecutter-data-science']' returned non-zero exit status 128.

I think it would be helpful to print the actual git output:

Cloning into 'cookiecutter-data-science'...
fatal: unable to access 'https://github.com/drivendata/cookiecutter-data-science/': SSL certificate problem: unable to get local issuer certificate

For what it's worth, I was then able to resolve the error (on windows) by setting the below:

git config --global http.sslbackend schannel
