unattended-installation: Don't accept passwordless VMs unless password is set as optional by libosinfo
Submitted by Fabiano Fidêncio
Link to original bug (#766731)
Description
Some install scripts don't have to have the password set, as the OpenSUSE case. But some of them do, as the Debian case. As this info, about the password being required or optional, is provided by libosinfo, we must make use of it for deciding whether the user can start the installation without setting a password for the VM or not.
