We create an unnamed user group with just the group creator as it's
member when trying to set the default. The pattern I've followed across
most of the acting_user additions is to just put the user declared
somewhere before the check_add_user_group and see if the test passes.
If it does not, then I'll look at what kind of user it needs to be set
to `acting_user`.
This commit introduced 'creator' and 'date_created'
fields in user groups, allowing users to view who
created the groups and when.
Both fields can be null for groups without creator data.
This commit adds a new group level setting can_manage_group
for configuring who can manage a group. This commit only adds
the field in database and make changes to automatically create
single user groups corresponsing to acting user
which will be the default value for this setting.
Fixes part of #25928.
This commit removes name, description, is_system_group and
can_mention_group fields from UserGroup model and rename
them in NamedUserGroup model.
Fixes#29554.
