[gnome-boxes] Save default libvirt connection machines on quit

[Zeeshan Ali Khattak <zeeshanak src gnome org>]

commit 25b57ee6adffb3804c6b817f7d563fe4528be6d4

    Save default libvirt connection machines on quit
    
    On quit, save and suspend machines belonging to default libvirt
    connection. This setting can be overridden by setting boolean prop
    'save-on-quit' to false in the source file. If disabled, the machines in
    question are only suspended but not saved.
