    network: Only share a new wifi connection if the user is allowed to
    
    Making a new connection available to other users requires being an
    admin, or entering an admin password.
    
    If we enable that option by default for new connections, we effectively
    prevent non-admin users from connecting to new networks when they go to
    the coffee shop without their laptop admin.
