Create a `MetricsRegistryRegistrationHandle` object that will manage the metric collection callback registration associated with the specified `original` handle. After creating this object, `original` will no longer manage the registration, and `original.isRegistered()` will be `false`. If `original` does not manage a registration when this object is created, then neither this object nor `original` will manage a registration.
