Switch to stestr

According to Openstack summit session [1], stestr is maintained project
to which all Openstack projects should migrate. Let's switch to stestr
as other projects have already moved to it.

While we're at it, we also fix the docs requirements and removed the
unused 'pypy' and 'cover' tox targets.
