    state the fact that NSX Service node is mandatory for Mirantis OpenStack

    - NSX cluster can successfully operate without Service node, but our
      tests show that creation of virtual interfaces fails, due to incorrect
      configuration of `replication_mode' setting in Neutron NSX plugin
      confguration file (plugin is configured to use Service node)
    - we need more work to be done to implement working Mirantis OpenStack
      with NSX cluster that operates without Service node
    - note that OpenStack itself can be used with NSX cluster that lacks
      Service node
    - while here add missing article
