[virt-tools-list] [PATCHv2 virt-viewer 07/10] kiosk: add --kiosk-quit option

[Marc-André Lureau]

In kiosk mode, it's useful to keep the app alive, even if the remote
session ended for example. Ie, we want to prevent the app from quiting
itself, even if the remote end closed, lost network, or crashed etc.
