This adds the import order extension to match what we have in the cinder
repo. This is a linting extension that will check that imports are in
the correct order and the correct grouping so they automatically get
flagged, and it won't be whether reviewers notice and decide to do
anything or not.
Cinder change was Ic13ba238a4a45c6219f4de131cfe0366219d722f for a little
more wordy reasoning.
Also includes updates for noqa tags. Newer version of the linters appear
to want these on the function definition line, not on the decorator
line.
