Using oc explain ClusterLogForwarder.spec.outputs.tuning.delivery is defined that AtLeastOnce is the default option--> - AtLeastOnce (default). But this is not correct because the default option is AtMostOnce

RHOL 5.9 

    1. oc explain ClusterLogForwarder.spec.outputs.tuning.delivery

DESCRIPTION:
    Delivery mode for log forwarding. 
     - AtLeastOnce (default): if the forwarder crashes or is re-started, any
    logs that were read before the crash but not sent to their destination will
    be re-read and re-sent. Note it is possible that some logs are duplicated in
    the event of a crash - log records are delivered at-least-once. -
    AtMostOnce: The forwarder makes no effort to recover logs lost during a
    crash. This mode may give better throughput, but could result in more log
    loss.     
    
    2. Default should be defined in AtMostOnce

    

AtLeastOnce is defined as Default.    

AtMostOnce should be defined as Default.
