I've gone through the 2 errors initially reported:
1. Concurrency issues with HA ports: fixed by https://review.openstack.org/#/c/257059/ (introduction of the ALLOCATING status for routers)
2. AttributeError: already referenced by https://bugs.launchpad.net/neutron/+bug/1605546
So this bug can be closed.
