Skip stack level hook for stack if prior stack level change set hook succeeded

For stack level hooks, customers are able to return a new status that allow stack level hooks that execute against a stack to skip with a successful status. The idea is that if a stack hook invoked against a change set succeeds, there is no need to invoke against the stack once the change set is processed.
