 * SwitchableImageStreamProducer adds the ability to 'bow out' to an ImageStreamProducer
 * Suppose we have SwitchableImageStreamProducer a and ImageStreamProducer b.
 * We want b to take over a's function. We would call a.switchTo(b) to move the consumers to b,
 * then remove a from the ImageStreamBroker and add b.
