8f02c9b540
Adds a new resource, designed to enable easy "stubbing out" of resources via the environment resource_registry. It takes any properties, and returns any attribute (as None), meaning it can be uses in place of "noop" nested stacks which dummy an existing resources by matching parameters/outputs to properties/attributes. Implements: blueprint noop-resource Change-Id: Idc485a9fcf7287030dda22f893486279be9e1a68
