packaging: setup: log setup events - add otopi upgrade

Log setup events for when otopi engine-setup-2 is used to upgrade
from a previous engine-setup-2 and from a legacy engine-setup.

Also change the text from http://gerrit.ovirt.org/15863 to not
mention otopi, so altogether we just log setup/upgrade/cleanup.
