Switch to using stestr

stestr is a fork of testrepository, designed specifically to concentrate
on being a dedicated test runner. [1] The testrepository project is
basically not active anymore and has several long standing bugs and
useablility issues. stestr is still actively maintained and fixes a
large number of those issues with testrepository.
