NetworkManager and PEERDNS=no

[Tom Horsley]

I keep seeing signs that "network" will someday disappear
entirely and I'll be forced to use NetworkManager, so the
first question I haven't been able to find an answer
for:

What is the "proper" way to setup a network connection
using nmcli which will get an IP via DHCP, but will ignore
the DHCP provided DNS and use a different DNS server specified
manually? (I can do it using techniques like chattr +i on
/etc/resolv.conf, but that isn't exactly "proper" :-).
