Earlier in Odoo, JS views were defined by defining 4 elements: View,
Controller, Model, Renderer. This was complex in some way, because we
wanted to inherit behaviour as well, so it was necessary to think along
multiple dimensions to understand how the code was running.
Then, with Owl, we rewrote some views, and simplified them: views were
now just a Component. Most of the common behaviour now came from the
generic View component that instantiated the concrete view with the
proper informations. In practice, views were still split in views
(which was the equivalent of the Controller of earlier views), Model and
Renderer
Now, this commit reintroduce the Controller, and change the way views
are defined: by an object with multiple metadata, and an (optional)
props function to compute the actual props used by the view.
As a result, views are now much easier to extend/modify.
