Following on from
ISIS-667, the other services (interaction, published now use UUID instead of string for transactoinId, java.sql.Timestamp instead of long for timestamps).
This ticket is to replace AuditingService2 with an equivalent AuditingService3 that uses these new types.
NB: this is a breakage of applib API, and according to semver, we ought to rev Isis to 2.0. I don't think this is justified however; the refactor is very simple for anyone that has used this API, and revving to 2.0 seems to be overkill. Better to address in the release notes for next 1.x release.
