Part of support for nested stacks and updates story To add nested stack support to Valet, make up for missing Heat resource Orchestration IDs in nested resources by generating a subset of Heat stack lifecycle scheduler hints for each resource in advance, store them as opaque metadata in Valet, then leverage the metadata at Nova scheduling time. Make additional accommodations in anticipation of complexities brought about by adding support for stack updates. To add a minimally viable amount of Heat `stack-update` support to Valet, significantly restrict the number of update use cases using a set of acceptance criteria. Skip holistic placement at `stack-update` time in favor of Valet's existing re-plan mechanism, placing or replacing resources one at a time, albeit still in consideration of other resources in the same stack hierarchy.
