-- Updates a stack using the input information that was provided when the specified change set was created. After the call successfully completes, AWS CloudFormation starts updating the stack. Use the < DescribeStacks> action to view the status of the update.
--
-- When you execute a change set, AWS CloudFormation deletes all other change sets associated with the stack because they aren\'t valid for the updated stack.
--
-- If a stack policy is associated with the stack, AWS CloudFormation enforces the policy during the update. You can\'t specify a temporary stack policy that overrides the current policy.
