For example, the tripleohelper/undercloud.py file appears to be a re-write of ansible and shade. While other parts, seem to relate to how nodepool works today.
Would you be open to the idea of porting some of this code to use ansible for remote code execution? Additionally, I would strong recommend using shade as your interface for openstack, over nova API directly. BTW have you looked at linch-pin[1]? I am sure there is some difference, but python-tripleo-helper looks very similar to linch-pin. Maybe it is possible to extend it.
