[IMP] website_forum: Add privacy

Add privacy on forum: public or private. If private, we must select
one group that has access.

For forum linked to eLearning course: the privacy of forum is the same
as the course. If the course is not yet published, the forum will be
invisible (unless we have the group group_website_slides_officer).

If a forum linked to a course is unlinked or removed, the forum will
become private and his group will be set to group_website_slides_officer.

All posts and tags have the same access rules as their linked forum.
