    Consider whether nodes have public network for net-checker config

    Public VLANs should be added into net-checker configuration only
    for nodes which have br-ex to be configured and only when cluster have
    more than one of such nodes.
    When there is only one such node in cluster, public VLAN cannot be checked
    as there is no sense to run data transmission test within one node.
