Extracted code from sync_users() into separate functions
in order to enable ad-hoc sheduling, and chunking.

It has never been guaranteed that settings.php would always be included
from inside the core\plugininfo\auth::load_settings() scope only.
Alternative fix would be to use $plugininfo->name but I think it is
better to be explicit here (same as we are explicit with setting names,
strings etc).
