Description of problem: Topology: 3 controller, 2 novacontrol, 2 compute, When runnning FFU upgrade procedure, there is an ImportError on novacontrol node, due to missing dependencies.
Version-Release number of selected component (if applicable):
python2-tooz-1.60.1-1.el7ost.noarch
Steps to Reproduce:
1. Deploy Rhos-10 and start FFU upgrade procedure to add novacontrol node from Rhos-11
2. Run ffwd-upgrade run command
3. Command fails with error: ImportError
Actual results:

Expected results:

Additional info:
Appears that openstack-nova doesn't require python-tooz >= 1.44.0 as required by the change that introduced the dependency in Pike [1]. I've pushed a change to the upstream RDO spec [2] that should correct this and I'll cherry-pick this downstream once it lands.
