ChangeNotification and ChangeNotificationCollection model classes missing in v6

[coinzz]

Expected behavior

Existance of these two classes under the package com.microsoft.graph.models. A removal of these classes has not been stated in the changelog. These are necessary to read ChangeNotifications from e.g. EventHubs and are still used in examples, e.g. here.

Actual behavior

Classes are missing and therefore serializer.deserializeObject(jsonPayload, ChangeNotificationCollection.class) can't be used.

Steps to reproduce the behavior

Download current version of graph 6.4.0

Thank you for reporting this.
This is a shortcoming of the new pipeline used to generate the new SDK and I've logged an issue at the source of this issue so we can start addressing it.
It's however going to take a while to be addressed end to end, and given enough customer demand for this, we might handcraft the missing types like we've done in dotnet.
