Review request for atlas, Radhika Kundam and Sidharth Mishra.


Bugs: ATLAS-4674
    https://issues.apache.org/jira/browse/ATLAS-4674


Repository: atlas


Description
-------

When we add/delete a classification from an entity, we send notification to ATLAS_ENTITIES so ranger tag sync works appropriately to facilitate Tag-based policy. This functionally seems to be broken and is a regression.

On further investigation, it is seen that the issue is caused by deferred action for classification propagation as the right notifications are sent when deferred action is disabled. 

Entity details for the notification messages are fetched from the entity cache which is not updated and lacks the new classification mapping. Hence, this patch clears the cache so that the entity is newly mapped from it's vertex and contains all the information.
