p2v: Add Configure Network button (RHBZ#1167921).

The old version of virt-p2v had a whole custom-written dialog which
interacted with NetworkManager over dbus.  After trying that approach,
it's really complex to get right.

Instead this button simply opens NetworkManager's connection editor.

This also adds nm-applet to the disk and starts it.  However nm-applet
does not display any visible indication -- probably because we are
lacking a system tray.
