Not sure about recovering your cluster on a 4.5 install with a 4.4 backup.
I would also like to know if that is possible.

As a separate note, if you really need to install 4.4 instead of 4.5; I
managed to install a 4.4.10 hosted engine recently by
- extracting the ova from the ovirt-appliance rpm
- mount the image with guestmount
- do : echo "exclude=postgresql-jdbc" >> /etc/dnf/dnf.conf in the image
- rebuild the ova and point the installer to it when asked for a custom ova

This stopped the installation playbook from upgrading to the unsupported
