Comment 11 for bug 1781121

- Fix involves - not executing /firstboot at ContrailVM creation,
  this will result in the following names for the ContrailVM

                mgmt ctrl-data vmware_physical_intf

single-intf ens160 -- ens192

multi-intf ens160 ens192 ens224
(ctrl-data)

multi-intf ens160 ens192 ens224
(pci/sriov)

  This change is done and saved in the ContrailVM vmdk at:
  /cs-shared/contrail-vcenter/vmdk/centos-7.5/LATEST

- When finding vmware_physical_interface, exclude PCI/SRIOV
  interfaces (driver_type should be vmxnet3)
