cloud-init-nocloud element for non-cloud image

Browse Source 
Disables cloud-init from querying EC2 metadata, or any cloud metadata
service. It keeps only the Nocloud and None data sources, which are both
expected to be "baked in" to an image.  This speeds up boot by 2 minutes
on hosts where cloud-init cannot reach the EC2 metadata service.

Configures cloud-init to only use on-disk metadata/userdata sources. This
will avoid a boot delay of 2 minutes while polling for cloud data sources
such as the EC2 metadata service.
