    Add lan9118 as valid nic for hw_vif_model property for qemu
    
    DocImpact
    This introduces an additional VNI so the hw_vif_model doc needs updating
    to reflect this at:

Title:
  Can't launch qemu instance with lan9118 nic type

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  When an image[0] has the property "hw_vif_model" set to "lan9118"
  instances can't be launched[1] even though the underlying hypervisor
  qemu allows this[2] nic for the ARM emulation, by way of
  architecture=armv7l and hw_machine_type=vexpress-a9a. I tried this on
  a devstack environment[3].
