Reputation events for Files and Urls

[maxhotta]

I would like to propose logging an Application Activity event for when a product on a device queries information from a backend system that generates Reputation values for files and urls.
Currently, a Reputation object exists in the schema, but appears to only be captured as an Observable with no other references in existing events.
The discussion is for whether these events belong in the core schema, a vendor specific extension, (or perhaps a different implementation).
