Merged pytest-repeat and pytest-stress

I merged pytest-stress and pytest-repeat and called it pytest-loop. Also added a fix for clearing previous reports so pytest-stress part did not keep appending results.

My merge completely changes how pytest-repeat reports results though. Is a merge a good idea or just leave it as a separate project?
