Extend Designated native RoleManagement events with old/new public keys #3389
Description
Summary or problem description
Issue migrated from #3386 (comment).
Designation RoleManagement events include only role and block height, whereas it would be useful for users to track the previous and updated set of designated public keys, exactly like it's done for CommitteeChanged events.
Do you have any solution you want to propose?
Extend Designation event with two arguments: old and new Arrays of public keys.
Where in the software does this update applies to?
- Native contracts
