Create Activation dbus object
Monitor the creation of new software version dbus objects and
create an activation dbus object SOFTWARE_OBJPATH/<ID>.
Save them in a persistent map with the corresponding version id,
add the real version id number to the map and to the dbus
object path once that's available.
