I was upgrading my lab from 4.2.0 to 4.2.1 RC and noticed that now an ansible playbook is executed during the upgrade instead of ovirt-host-deploy upgrade process.

I think integration team missed this change being discussed but I guess that whoever did this change ensured that the playbook do also all those stuff that ovirt-host-deploy did when upgrading the hosts. I remember we had some code executed around vmconsole, hosted-engine and vdsm PKI related stuff.
