Migrating from ifupdown to netplan

Registered by Mathieu Trudel-Lapierre

Deprecate ifupdown and previous-generation networking tools in Ubuntu for the 17.10 release. Target a unified network stack of netplan, networkd, and network-manager across all 17.10 images in preparation for the 18.04 LTS, phasing out ifupdown.
