Subject: [PATCH 12/15] subman: Add DBus API to subscribe for updates on
 already registered system

It's possible an admin may have registered their system without
attaching any subscriptions to it.

At the moment, gnome-settings-daemon only provides a way to register
and subscribe in one step.

This commit adds an API to support doing the last half of the process
on its own.
