A recent change making nova-metadata-api work with wsgi [1] moved the vendordata plugin parameters to the nova::metadata manifest. While this is conceptually correct as nova-metadata is the one that should be using this parameters. In practice the parameters are also used in compute drivers (in the ironic driver, for instance), thats why we should split them to be able to deploy nova-metadata-api separate from nova-compute.
