Look at https://review.openstack.org/#/c/249711/17/manifests/init.pp
rpc_backend is now defaults to $::os_service_default (which will unset the param if no value, that is the default in OpenStack).
It was set to 'rabbit' before.

I don't see yet where is the issue because Oslo messaging is using 'rabbit' as rpc_backend default value.
