This commit refactors get_realm_user_groups_for_dropdown_list_widget
function to use "group_permission_settings" module instead of
passing variables like "allow_internet_group", etc. individually
for each settings.
We lose some test coverage due to this commit, but that would be
fixed when we add some more group-based settings and allow groups
other than system groups in the group based settings.
This directory contains scripts that are used in building, managing,
testing, and other forms of work in a Zulip development environment.
Note that tools that are also useful in production belong in
scripts/ or should be Django management commands.
