Cloud-init uses the "datasource" of the EC2 Metadata service, that Openstack provides a workalike for. That metadata service has things like "instance-id" and "hostname" that are useful. cloud-init uses instance-id for "run-once-per-instance" functionality. cloud-init also gets user-data from the datasource, and that is very useful for initializing images with information provided at launch time by the user. If you enable config-drive in openstack, then cloud-init will find the same data above from the config-drive, and wont bother looking for the ec2 metadata service.
