Fix stestr configuration

.stestr.conf was missing, and in the lower-constraints tests we
weren't getting stestr installed, probably because we were using an
older version of oslotest that didn't depend on it. We should have
an explicit dep on it anyway so it is added to test-requirements.

Some old testr cruft is also cleaned up.
