Switch to Overcloud with Network isolation been setup via TripleO Master branch

UPDATE 09/23/2016

 Bug 1622683 gets status "Fix Released". Master's delorean trunk 09/23 works for me. So you shouldn't have to apply workaround - redeployment works
Already  tested.

END UPDATE

This post follows up TripleO deployment of 'master' branch via instack-virt-setup
Launchpad bug "Updating plans breaks deployment" https://bugs.launchpad.net/tripleo/+bug/1622683  still has status "In Progress" so to be able redeploy overcloud the workaround from https://bugs.launchpad.net/tripleo/+bug/1622720/comments/1  would be applied
**************************
Redeployment
**************************

[stack@instack ~]$ openstack stack delete overcloud
[stack@instack ~]$ . stackrc
[stack@instack ~]$ mistral environment-delete overcloud
   Request to delete environment overcloud has been accepted.
[stack@instack ~]$ swift delete --all

Add NAT Default VNIC to each of bare metal nodes (VMs)
To enable Internet connectivity from Controller after
overcloud deployment at the moment when "overcloud" stack got
gracefully deleted and status of bare metal nodes (VMs)  is down
