Description

Currently, CNI isolator will cleanup unknown orphaned containers in an asynchronous way (see here for details) during recovery, that means agent recovery can finish while the cleanup of unknown orphaned containers is still ongoing which is not ideal. So we need to make CNI isolator recovery waits until unknown orphan cleanup is done.
