This change duplicates the ideas started in with the placement-perfload job and builds on it to create a set of nested trees that can be exercised. In placement-perfload, placeload is used to create the providers. This proves to be cumbersome for nested topologies so this change starts a new model: Using parallel [1] plus instrumented gabbi to create nested topologies in a declarative fashion. gate/perfload-server.sh sets up placement db and starts a uwsgi server. gate/perfload-nested-loader.sh is called in the playbook to cause gabbi to create the nested topology described in gate/gabbits/nested-perfload.yaml. That topology is intentionally very naive right now but should be made more realisitc as we continue to develop nested features. There's some duplication between perfload.yaml and nested-perfload.yaml that will be cleared up in a followup.
