Attempt to verify patch for "metadata service PicklingError" on TripleO QS Master (Pike) via HA overcloud deployment

UPDATE  07/07/2017
See
1) Change abandoned by Dan Smith (dms@danplanet.com) on branch: master
https://review.openstack.org/#/c/479325/
2) This should be bug 1702150
https://bugs.launchpad.net/nova/+bug/1702150
3) Patch proposed by bug 1702150   updates base.py in same way as Dan Smith
    did in abandoned patch (1).
https://bugs.launchpad.net/nova/+bug/1702150/comments/1
END UPDATE

Perform HA overcloud deployment via TripleO QuickStart  Master (Pike) branch
via :-
$ bash quickstart.sh -R master  --config config/general_config/pacemaker.yml  --nodes config/nodes/3ctlr_2comp.yml  $VIRTHOST
 to avoid waiting for commit's appearance in Delorean RDO trunk for Master.
 Proceed as usual :-

[root@overcloud-controller-0 ~]# openstack flavor create --public m1.small --id 2 \
  --ram 2000 --disk 20 --vcpus 1 --rxtx-factor 1

[root@overcloud-controller-0 ~]# openstack keypair create oskey070417 > oskey070417.pem

[root@overcloud-controller-0 ~]# openstack  network create ext-net --external \
--provider-physical-network datacentre  --provider-network-type flat
