doc: Add new "Networking Setup" node for the main setup options.
This should make it easier to find how to get started setting up networking. * doc/guix.texi (Networking Setup): New section. (Networking Services): Remove 'static-networking-service', 'dhcp-client-service-type', 'network-manager-service-type', 'connman-service-type', 'wicd-service', 'modem-manager-service-type', 'usb-modeswitch-service-type', and 'wpa-supplicant-service-type'.
