* An application can be notified when its configuration properties are modified

* PropertiesAdminUpdateCallback and register it with the facet. The facet
* implements the class NativePropertiesAdmin, so the application needs to
* downcast the facet to this type in order to register the callback.
*
* For example:
*
* \code
* Ice::ObjectPtr obj = communicator->findAdminFacet("Properties");
* assert(obj); // May be null if the facet is not enabled
* NativePropertiesAdminPtr facet = NativePropertiesAdminPtr::dynamicCast(obj);
* PropertiesAdminUpdateCallbackPtr myCallback = ...;
* facet->addUpdateCallback(myCallback);
* \endcode
*
* Ice ignores any exceptions raised by the callback.
