Detailed bug description: During execution of longevity test on MOS 9.0, I've found a lot of warnings from Neutron about resource_versions dictionary:

Steps to reproduce: 1. Start any activity on cluster (run Neutron rally)
Actual result: 1. A lot of traces during execution
Reproducibility: 100%
Workaround: N/A
Impact: Unknown. I do not know how Neutron use this dictionary.
Description of the environment: * MOS 9.0, build 227 * 10 baremetal nodes (12 CPU, 32GB RAM) * Compute: KVM * Network: Neutron with VLAN segmentation * Ceph RBD for volumes (Cinder) * Ceph RadosGW for objects (Swift API) * Ceph RBD for ephemeral volumes (Nova) * Ceph RBD for images (Glance)
