Recent changes in the default configuration of cloud-init in Ubuntu cause warnings when the Ec2 datasource is used on non-Amazon clouds, see https://bugs.launchpad.net/cloud-init/+bug/1660385 We explicitly select the previous behavior when an Ec2 datasource is desired.

cloud-init-datasources
Configures cloud-init to only use an explicit list of data sources.
Cloud-init contains a growing collection of data source modules and most are enabled by default. This causes cloud-init to query each data source on first boot. This can cause delays or even boot problems depending on your environment.
Including this element without setting DIB_CLOUD_INIT_DATASOURCES will cause image builds to fail.
