 From the n-cpu logs this is the TypeError:

It looks like you're missing this change in whatever version of 
oslo.versionedobjects you have in your CI:

https://review.openstack.org/#/c/202200/

That should be in o.vo 0.6.0, latest is 0.7.0.  What version of 
oslo.versionedobjects is on the this system?  It would be helpful to 
have pip freeze output.
