don't install tests into the binary distribution

[evgeni]

this tries to install a "tests" python package, which we don't own.
at the same time, also exclude docs and contrib as done in the PyPA
sample project [1]

Thank you @evgeni

[evgeni]

Thanks @omaciel, will you do a release to PyPI too? :)

[omaciel]

@evgeni I can but it would only support Python 3. Is that cool with what you need?

[evgeni]

Nope :(
Need it for nailgun, which we use inside ansible, which is not really py3 ready yet.

[omaciel]

@evgeni one way would be to create a new version off the python2 branch...

[evgeni]

@omaciel if that's not too much ask, that would be great!

[omaciel]

@evgeni done. Version 2.1.2 will include only the change you submitted.
