A simple use case is user synchronization;
a) if we want to have a notification task for each user creation/update coming from sync task we can configure notification task to generate notification on this event [SyncTask]:[user]:[resourceName]:[create]:[SUCCESS].
b) But if we do not want to have too many notifications, like point 1, we can configure notification to create a notification task only when synchronization job finishes, setting notification event to [TASK]:[SyncJob]::[SyncJob]:[SUCCESS] instead of [SyncTask]:[user]:[resourceName]:[create]:[SUCCESS].
In case of a large number of users to synchronize b is preferable, and cumulative notification is sent.
Improve notification messages to show a better and more complete notification message generated from jobs like SyncJob or PushJob and also provide new mail and text templates useful for use case exposed above.
