Description of problem:

Ethernet interface eth1 supposed to support vm/data VLAN tagged network connection to Controller/Network Node doesn't become a port of OVS bridge br-eth1. Br-eth1 OVS bridge is not configured on Compute node. File openvswitch_agent.ini is missing required lines, ml2_conf.ini is absent at all. So, neutron-openvswitch-agent at start up is unable to configure required bridges and ports on Compute Node.

Compute Node :-
1.Block is absent on Compute
Bridge "br-eth1"
        Port "br-eth1"
            Interface "br-eth1"
                type: internal
        Port "eth1"
            Interface "eth1"
        Port "phy-br-eth1"
            Interface "phy-br-eth1"
                type: patch
                options: {peer="int-br-eth1"}

2.Block is absent on Compute
Port "int-br-eth1"
            Interface "int-br-eth1"
                type: patch
                options: {peer="phy-br-eth1"}
 
OVS/VLAN configuration on Compute node should be done manually via updating
required files in /etc/neutron/plugins/ml2 folder and copying over from Controller ifcfg-br-eth1 and ifcfg-eth1 into /etc/sysconfig/network-scripts
folder.

Afterwards :-

# openstack-service restart
# chkconfig network on
# systemctl stop Network Manager
# systemctl disable Network Manager 
# service network restart

brought Compute Node's OVS configuration to expected status.

Version-Release number of selected component (if applicable):

openstack-packstack-puppet-7.0.0-0.10.dev1682.g42b3426.el7.noarch
openstack-packstack-7.0.0-0.10.dev1682.g42b3426.el7.noarch

How reproducible:

Steps to Reproduce:

1.Update attached file for Controller/Network && Compute two node deployment
  Set :-
  CONFIG_UNSUPPORTED=n
  CONFIG_STORAGE_HOST=Controller's-IP 
 
2.packstack answer-file=./answerVLAN.txt

3.SSH to Compute node and run `ovs-vsctl show` right after packstack
  completion to make sure that nothing was done by packstack run.

Actual results:

Manual OVS configuration is required on Compute Node(s)

Expected results:

Packstack did OVS configuration properly on Compute Node(s)
As,actually, happens via same answer-file on RDO Kilo.
