Comment 1 for bug 1175580

Note that project_id is a number (tenant_id in the API), and actually needs to be passed in a different field. So it isn't simply putting the id in the 'tenant_name' field and having it work. Instead we need to look for both tenant_name and/or tenant_id and make sure that when we are making a request we put the value into the right request field.

This probably also needs changes to goose, to be able to support this either/or semantics.
