module-setup.sh: enable vlan on team interface
    
    Dracut has switch network-legacy to network-manager by default, which makes
    vlan on team easy. So it can be enabled.
    
    Testing network topology with two VMs.
    VM1
                ens2-\         /----> VLAN8 (192.168.120.50)
                      ---> team0
                ens3-/     (192.168.122.10)
    
    VM2
                ens2-\         /----> VLAN8 (192.168.120.100)
                      ---> team0
                ens3-/      (192.168.122.20)
    
    Both of ens2/ens3 in VM1/VM2 are connected to virbr0.
    
    During test, dump target is set as root@192.168.120.100:/var/crash
