support loopback interface

Browse source 
Support managing the loopback interface through NM as the users want to
set the proper mtu for loopback interface when forwarding the packets.
Additionally, the IP addresses, DNS, route and routing rules are also
allowed to configure for the loopback connection profiles.

switch.
* dns: support specifying DNS-over-TLS server name (SNI) for static
name servers. Only works with systemd-resolved plugin.
* Add support of loopback interface and a new connection type "loopback". On D-Bus,
the loopback interface now has the "org.freedesktop.NetworkManager.Device.Loopback"
interface instead of org.freedesktop.NetworkManager.Device.Generic".
Loopback handling is special in that when the NetworkManager profile is
deactivated, the interfaces will still be up and configured with a 127.0.0.1
address.
