Migration to new event defination for OpenONU adapter

     This change is for the migration of alarms and KPIs for earlier
     separate defination of AlarmEvent and KPIEvent to a generic format
     called Event where it could be an alarm or a KPI event

     An event manager adapter_events handles the event submission.
