mod_http_admin_api: restructure group-related info in API
- Return the members of the group right in the get_group_by_id
call. This is an O(1) of extra work.
- Remove the groups attribute from get_user_by_name as that is
O(n) of work and rarely immediately needed.
The replacement for the group membership information in the user
is for now to use the group API and iterate; future work may fix
that.
