[gnome-software/wip/rancell/ubuntu-3-20-rebase: 6/12] Show a notification if any live-updatable apps needs restarting



commit 75fef1a03b4468c41e1f645fc00cde37741c5395

    Show a notification if any live-updatable apps needs restarting
    
    This covers the case where an xdg-app might need restarting because of the
    runtime having a security update.
    
    We don't force a shell restart for all cases as this is overly draconian and
    this extra step seems like the right thing to do.
