Add nova-metadata template

This is needed because currently we're not generating
nova_metadata_vip or nova_metadata_nodes_ip, and a service profile is
required for that. Unfortunately, currently puppet-nova only deploys
osapi and metadata through the same manifest, so this profile doesn't
really inject any puppet code. We can make this more elegant later.
