Bug 1124593 reported that ssh host keys were not being created, and the
lack of seed metadata files was the cause. Add those files and remove
the workaround.

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.
