Public bug reported:
cloud-init v. 18.4-0ubuntu1~16.04.1 in -proposed automatically renders
network configuration from Azure's IMDS by default instead of fallback
config of dhcp on eth0. This represents a difference in behavior from
current Xenial.
On Xenial Azure, Ubuntu cloud images have udev scripts to handle network
hotplug. Azure datasource has the ability to read full network config from
their IMDS service and render hotplugged devices as well as remove the
cloud-image default scripts.
Make the cloud-init hotplug behavior configurable and default it to off
in Xenial.
