    notify the plugin only on status updated

    If the status of the firewall group is consistent with the status
    to be updated, there is no need to notify the plugin to update the
    status.
    The processing of the agent requires a certain amount of time. If
    firewall group is updated during this period, updating the firewall
    group status at this time may cause the firewall group to be in an
    incorrect state.
