Subject: [PATCH] [#428] cmd/node: Trigger local trust controller on new epoch

Implement and call `initReputationService` func that constructs local trust
storage and controller, and subscribes the controller on new epoch
notification. Event handler calls `Controller.Report` method to process
collected values.
