Title:
  DuplicateOptError: duplicate option: rpc_backend

Status in OpenStack Neutron (virtual network service):
  Invalid

Bug description:
  I'm trying to run devstack compute node (nova-compute + neutron-agt)
  using stable/juno version of openstack components.

  Unfortunately, I cannot start neutron-agent because of this error:
  python /usr/local/bin/neutron-ofagent-agent --config-file 
  Traceback (most recent call last):
    File "/usr/local/bin/neutron-ofagent-agent", line 10, in <module>

      raise DuplicateOptError(opt.name)
  oslo_config.cfg.DuplicateOptError: duplicate option: rpc_backend
  q-agt failed to start

  I had inspected both configuration files and found no duplications of
  "rpc_backend" parameter.
