ifup_vhost need to use "ip addr show" rather than ifconfig

Using build-51 and contrail-ansible-deployer to deploy on centos74.
On node restart unable to login to the host and observed the below errors on /var/log/messages
FYI net-tools package doesnt come pre-installed on minimal-centos74 we should either mandate installation of net-tools or use an alternative command for ifconfig.
