Changes without compatibility

Removal of older pre-release packages from PyPI

As announced in #4360, we have removed pre-release wheels earlier than v6.0.0rc1 from PyPI. Those version wheels can be found at the GitHub release page of every version, and can be installed by specifying -f option:

pip install --pre cupy-cuda101 -f https://github.com/cupy/cupy/releases/v6.0.0rc1
