Enforce import style with isort
I would like to propose to enforce import style using isort. The idea is to configure isort to use a style that is the closer to our current practice. I propose this setup:
isort -m VERTICAL_GRID -p trytond
and to add to reviewbot this checking command:
isort -m VERTICAL_GRID -p trytond -c `hg status -S | cut -d " " -f2 -`
So the idea is to progressively standardize the import. I do not think it will create a big load for back-porting fixes because it is quite rare to have to modify the imports in bugfix.
