Align to openstack python package index mirror

Some modules we developed will not be updated to pypi in time, meanwhile,
jenkins will poll packages from openstack mirror, so it is worth to be
set as default index in tox.

User can use -i option in tox cli to change default index server to any
popular or his favorite.
