Comment 1 for bug 1881228

I believe this may be solved by removing /%(tenant_id)s from Nova endpoints. See
https://opendev.org/openstack/kolla-ansible/commit/82551a2bfb62049cf7503fd2a543697ff7f4b7d4 for how this was changed in Kolla Ansible. If this is not an appropriate solution we would need to allow to provide a custom Nova endpoint URL via blazar.conf. I don't remember whether that's already possible or not.
