Vcenter-as-compute: Compute VM not receiving IP and hostname

[Sarath]

This is seen on Vcenter-as-compute sanity with Ubuntu 16-04 (newton)

This works good when using ubuntu 14-04 (mitaka) and debugging shows different interface name when updated
into /etc/network/interfaces gets IP

root@ContrailVM-24-26:~# cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

auto ens160
