REVISION SUMMARY
  This will tell pip et al to call our setup.py for the majority of
  packaging concerns, but also gives us a place to put standard config
  stuff like black.
  
  This was previously D9833 <https://phab.mercurial-scm.org/D9833>, but was rolled back due to test
  breakage. nbjoerg thinks that breakage is now resolved, so we're
  trying again.
