qa/tasks/keystone.py: install python3

install python3 for keystone's tox based test otherwise python34 would
be installed, and keystone's tox based test does not support python34.

this change is not cherry-picked from master, as our python bindings are
now built with python3.6, so python3.6 is always used. it's supported by
keystone's test.
