Edit nmcli command to show additional information about the routes
(both route4 and route6).
If there is information about next hop or metric in the route
structure it will be shown in addition to destination and prefix.
Invoke Reload() asynchronously and run the main loop. In this way, the
polkit agent built into nmcli can be used to authenticate the reload
request.
