Code Issues Proposed changes
vmware-nsx/neutron/tests/unit/ofagent/test_ofa_neutron_agent.py
Ihar Hrachyshka 5c376126a2 Refresh rpc_backend values in unit tests to those from oslo.messaging 
Though old values are supported via compatibility transport aliases [1],
it's better to stick to those values that are officially supported by
oslo.messaging.
