Description of problem:
Scale out failed from 1 ctrl, 1 compute and 1 ceph to 1 ctrl, 2 computes and 1 ceph. Running a baremetal environment without using networks isolation.

Version-Release number of selected component (if applicable):
openstack-tripleo-heat-templates-0.8.6-44.el7ost.noarch

How reproducible:


Steps to Reproduce:
1. Initial deploy command:
openstack overcloud deploy --control-scale 1 --compute-scale 1 --ceph-storage-scale 1 --plan overcloud  --neutron-public-interface eth1  --control-flavor control  --compute-flavor  compute  --ceph-storage-flavor storage

2. Scale out to 2 computes:
openstack overcloud deploy --control-scale 1 --compute-scale 2 --ceph-storage-scale 1 --plan overcloud  --neutron-public-interface eth1  --control-flavor control  --compute-flavor  compute  --ceph-storage-flavor storage


Actual results:
Stack update fails

Expected results:
Stack update succeeds.
