This really is a bug in oslo. To be clear there is no actual error here just a spurious log message. The code underneath nova tries to speculatively load the etcd driver and produces an error when it is not available. The etcd driver is not needed if etcd is not being used, which in this case it is not. See the dicussion on the comments here https://review.opendev.org/c/openstack/openstack-ansible-os_nova/+/765336 Jonathan.
