Add OVA/OVF import tools and virtio-win downloader

Two implementations of the same OVA/OVF import flow: a Python version that parses the OVF with ElementTree and detects UEFI, and a shell version using xmllint that handles multi-disk appliances. Both check free space on the target storage before importing. download-virtio-win-progress.py fetches the latest virtio-win ISO, skipping the download when the local copy is already current.
