public interface OperatorEventGateway

The gateway through which an Operator can send an OperatorEvent to the OperatorCoordinator on the JobManager side.

This is the first step in the chain of sending Operator Events from Operator to Coordinator. Each layer adds further context, so that the inner layers do not need to know about the complete context, which keeps dependencies small and makes testing easier.

     OperatorEventGateway takes the event, enriches the event with the OperatorID, and
         forwards it to:
     TaskOperatorEventGateway enriches the event with the ExecutionAttemptID and
         forwards it to the:
     JobMasterOperatorEventGateway which is RPC interface from the TaskManager to the JobManager.
