The product IDs generated for Azure images are not consistent with what's been
used for EC2 and Openstack. The extra ":azure" part at the end is not recognised
by Juju.

The scripts used to generate the Azure simplestreams metadata need to be changed
to produce output that is consistent with the format used for other cloud vendors.
