PURPOSE
Allow alias domains to be multiple, notably to be used in a multi company
environment where each company has its own alias domain.
SPECIFICATIONS
Update fields used in form views. Use 'alias_domain_id' instead of domain
that is now simply a related on 'alias_domain_id.name'. To ease UI we add
a placeholder on this field as it is now writable e.g. in multi domains
environment. Avoid unwanted configuration change by making it generally
no_open / no_create_edit.
In project, remove an unnecessary field adding complexity for few real use
case now that aliases are more open to configuration.
