Lazy load resources in parser.Stack

Registered by Jason Dunsmore

Right now, instantiating a Stack object loads all resources. This is sometimes unnecessary (eg. https://review.openstack.org/#/c/39760/6/heat/engine/service.py). parser.Stack should only load resources if the method requires the resources to be loaded, as is the case in parser.Stack.stack_task().
