* Impose the use of the dedicated tour utils to factorize and harmonize
the way tours behave on the ecommerce.
* Introduce new utils when it seems adequate and useful.
This will reduce incoherences and non determinism in e-commerce tours,
and ease future tasks refactoring the e-commerce design and process
(since we'll be able to restrict most changes to the utils instead of adapting
all the tours one by one).
