Subject: [PATCH] Add a CLOUDPACKAGE variable to contain a list of targets for
 post-install packaging cloud provider images.

Add a 'gce-package.sh' script to generate the final output
image ready for upload to the GCE platform.  Right now, this
is the only image that has a specific output format (GNU-tar),
and this implementation is expected to be temporary.

This is not directly connected to the other release targets.
