On a default PVE installation no storage has import enabled, so the installer always fails without manual configuration. Add helper functions to check whether a storage supports import, enable it on a suitable directory-type storage via the PVE API, and optionally restore the original configuration after install. These can be used by the frontend to prompt the user before making changes.
