Description of problem:
Undercloud keepalived instance collides with the keepalived deployed on the Openshift overcloud:

Checking /var/log/messages on undercloud and master nodes we can a huge amount of 'bogus VRRP packet received' messages:

Version-Release number of selected component (if applicable):
openstack-tripleo-heat-templates-9.0.0-0.20180831204457.17bb71e.0rc1.el7ost.noarch

How reproducible:
100%

Steps to Reproduce:
1. Deploy Openshift via OSPd
2. Check /var/log/messages on undercloud and master nodes

Actual results:
Keepalived on undercloud and master nodes reports bogus VRRP packet messages because keepalived configures the same vrrp instances:

on undercloud:

(undercloud) [stack@undercloud-0 ~]$ docker exec keepalived cat /etc/keepalived/keepalived.conf
# This file is managed by Puppet. DO NOT EDIT.
global_defs {
  notification_email {
    root
  }
  notification_email_from keepalived
  smtp_server localhost
  smtp_connect_timeout 30
  router_id undercloud-0
}

static_ipaddress {
  
}

vrrp_script haproxy {
  script   "test -S /var/lib/haproxy/stats && echo "show info" | socat /var/lib/haproxy/stats stdio"
  interval 2
  weight   2
}
vrrp_instance 51 {
  virtual_router_id 51

  # Advert interval
  advert_int 1

  # for electing MASTER, highest priority wins.
  priority  101
  state     MASTER

  interface br-ctlplane

  virtual_ipaddress {

      192.168.24.3 dev br-ctlplane

}
vrrp_instance 52 {

  state     MASTER

  interface br-ctlplane

  virtual_ipaddress {

      192.168.24.2 dev br-ctlplane
  }

  track_script {
  haproxy
  }




}

on overcloud:
[root@openshift-openshiftmaster-0 heat-admin]# docker exec keepalived cat /etc/keepalived/keepalived.conf
# This file is managed by Puppet. DO NOT EDIT.
global_defs {
  notification_email {

  }
  notification_email_from keepalived@localdomain
  smtp_server localhost
  smtp_connect_timeout 30
  router_id openshift-openshiftmaster-0
}

static_ipaddress {
  
}

vrrp_script haproxy {
  script   "test -S /var/lib/haproxy/stats && echo "show info" | socat /var/lib/haproxy/stats stdio"
  interval 2
  weight   2
}
vrrp_instance 51 {
  virtual_router_id 51

  # Advert interval
  advert_int 1

  # for electing MASTER, highest priority wins.
  priority  101
  state     MASTER

  interface eth0

  virtual_ipaddress {

      192.168.24.9 dev eth0
  }

  track_script {
  haproxy
  }




}
vrrp_instance 52 {
  virtual_router_id 52

  # Advert interval
  advert_int 1

  # for electing MASTER, highest priority wins.
  priority  101
  state     MASTER

  interface eth0

  virtual_ipaddress {

      192.168.24.9 dev eth0
  }

  track_script {
  haproxy
  }




}
vrrp_instance 53 {
  virtual_router_id 53

  # Advert interval
  advert_int 1

  # for electing MASTER, highest priority wins.
  priority  101
  state     MASTER

  interface eth0

  virtual_ipaddress {

      192.168.24.6/32 dev eth0
  }

  track_script {
  haproxy
  }




}


Expected results:
Different vrrp instances on undercloud and overcloud.
