// 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.
