[REF] crm: ensure automatic assignment works out of the box

GLOBAL PURPOSE

Ability to have salesmen belonging to several sales team is a core requirement
of CRM. It is therefore moved from website_crm_score to crm along with cleaning
and behavior improvement. Automatic lead assignment is also moved and cleaned.

SPECIFICATIONS

Assignment max being set to 0 means member is out of automatic assign process.
In that case assignment information (domain in form view, gauge in kanban
view) are hidden to lighten member form view.

Its default value is now set to 30. It means that newly created members by
default are available for automatic assignment.
