pytest-runner deprecated usage

[edobez]

pytest-runner is used in a deprecated way: from setup_requires. Probably most of the times this is not an issue, but in my case when installing this package using pip, the setup_requires step tries to get pytest-runner if not already available. The problem is right here: the way setup_requires tries to get the missing package is not honoring pip configuration, such as different index, certificates, proxies, etc. This fails the download in my case.

The workaround I found is to install pytest-runner first using pip, so it will be found in the setup_requires step.
