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.

Description
===========

This module measures the rate at which text messages are exchanged, and their
encryption status.

::: {.alert .alert-warning}
This module can leak information about your users’ behaviour to anyone who can
access these statistics, so avoid enabling it on a server with few users.
