Comment 4 for bug 1872205

What is the driver used? Looks like etcd3?
https://docs.openstack.org/tooz/rocky/user/compatibility.html

The implementation is using create_group / join_group which probably raises NotImplemented errors.
https://github.com/openstack/designate/blob/master/designate/coordination.py#L89

I am wondering if maybe the coordination driver is started successfully, but the backend does not support what Designate is trying to do, making Designate think that it wasn't connected successfully.
