Import patches-unapplied version 2.457 to ubuntu/artful-proposed

Imported using git-ubuntu import.

Changelog parent: 62cc84825d

New changelog entries:
  * Enable systemd-networkd by default.
    - Usually, netplan's systemd-generator enables systemd-networkd and
    systemd-networkd-wait-online on boot. But netplan configuration is not
    yet generated at that point by cloud-init. Cloud-init generates in the
    network-pre.target and expects the network.target /
    network-online.target to work. These are already part of the ongoing
    systemd transaction, thus cannot be injected into the boot-sequency by
    cloud-init local mode. Therefore make sure cloud images include
    networkd in the initial boot transaction.
    - src:systemd will shortly not enable networkd unconditionally by
    default.
  * Drop ifupdown e-n-i configuration files, no longer used.
