    libvirt-machine-props: Allow rebooting saved VMs
    
    Currently, if user changes the properties of a saved VM that require
    reboot to take effect, we don't offer user the option to reboot. As a
    result the properties are not in effect when user restores the VM, which
    is contrary to what she/he will expect.
    
    This patch:
    
    * offers user the option to reboot saved VMs.
    * if user chooses to reboot, the VM is first restored and then rebooted.
