    [KYUUBI #5731][K8S] Support to cleanup the spark driver pod with specified cleanup strategy
    
    # :mag: Description
    
    ## Describe Your Solution ๐Ÿ”ง
    
    A new feature introduced from #5714 supports kyuubi to clean up spark driver pods automatically, but all pod would be clean up without considering app's terminated state.
    This PR make user can chose which pods should be delete by setting up a cleanup strategy.
