*website_crm_partner_assign, website_customer
Before this commit, some models would create their own `website_published`
field rather than using the `website.published.mixin` mixin which should be
used instead.
That was done to be able to override the default value of the boolean.
This commit simply adds the possibility to override the default value of the
mixin field.
Also, help and string could simply be added on xml views rather than overriding
the field.
Purpose of this commit is to give description more "business oriented"
because those descriptions appears in Odoo Studio which is supposed to be used by end users, not only by developers.
