Explicitly define the name of the os- packages

Updates the configurations for os-apply-config, os-refresh-config,
os-collect-config, and os-cloud-config so that they are explicity
set. The 'core' template for these projects mostly works except
that the name field was previously wrong because these projects
don't have the 'openstack-' prefix on their RPMs.
