Description: Which data sources should be searched?
 Cloud-init supports searching different "Data Sources" for information
 that it uses to configure a cloud instance.

 Warning: Only select 'Ec2' if this system will be run on a system with
 the EC2 metadata service present.  Doing so incorrectly will result in
 a substantial timeout on boot.
