Add Python 3 only classifier

kajinamit · kajinamit · commit ef4991dc7aa2 · 2022-02-08T23:16:05.000+09:00
Python 2 support was removed during Ussuri cycle. This change adds
the classifier to clearly state that only Python 3 is supported.

This allows us to keep the setup.cfg file in cinder and the one in
cinderclient more consistent.
