The cells RPC API version has to be less than 1.35, see:
https://github.com/openstack/nova/blob/86fe90f7056432416ea3c2335ea8c2ad6e16b79a/nova/cells/rpcapi.py#L117
You'll have to fake this out on a single node devstack to recreate probably.
Try setting this in your nova.conf:
[upgrade_levels] cells=kilo
Since the kilo rpc api version is 1.34.
You'll have to restart the cells service for that to take effect.
