Add project_name to nova/placement client config

With missing 'project_name' config in adoption jobs nova api
service requests fails with [1] as the service users created[2]
in adopted cloud don't have default_project_id set. And user is
also not updated if it already exists[3].

It's not seen in the non-adoption jobs as users created
have default_project_id set[4]. This patch explicitly
set's the project_name config to resolve the issue.
