Sorting pods in a 5-stage template would be helpful

Ref: #685

Because individual pods are kept as a map when creating pod-based templates, the order of pods in the template (and ultimate creation order within the blueprint scaffolding process) is unpredictable.

As a short term fix, we can sort the pods so that at least the order is predictable if not controllable.
