  cibuildwheel CI tests failing on Azure for windows
  `cibuildwheel` CI tests which are using the sample configuration in README are failing on Windows following Azure update to support python 3.8
  
  Given the number of CI providers now tested, I guess we can try to test `cibuildwheel` on python 2.7, 3.5, 3.6, 3.7 and 3.8 without too much overhead on test time by dispatching the python versions running `cibuildwheel` across CI providers.
