setup.py is using setup_requires which is causing issues with pip in certain environments

[mervynrussell]

We use pip to install packages for our build pipelines and for vendoring packages prior to deployment onto our cloud environment. The use of setup_requires bypasses the pip installation and means we have to hack around with our pipelines in order to fix these up. Is the dependency on pytest-runner for setup of cfn-flip actually required and if not can it be removed? pip user guide actively discourages use of setup_requires.

It's interesting that pytest-runner has this statement to use setup_requires in their documentation:

https://pypi.org/project/pytest-runner/

And the latest version 5.0 launched this year still states to use this technique.

I will test moving this dependency that is just used to build the package to test_require

Thanks Rafael. Yeah, I saw that in their docs too when we first started using cfn-flip and encountered the problem. Note pytest-runner documentation does outline how to add it to setup_requires conditionally if you find that test_require doesn't work for you.

Fixed in #77 :)
