cli: allow being called as ifup/ifdownlr/alternatives-two

Use that as an alias of "nmcli dev connect" or "nmcli dev disconnect"

Don't advertise it really because it's not really a preferred way for
doing things, but it will help transitioning away from legacy iniscripts
while still keeping some compatibility.
