While creating agent based ISO image using "openshift-install" throwing an error, when we run "agent create image" for second time on same cluster. 

    OCP Build Version: 4.18 RC build

    Always

    1. Run this command "./openshift-install agent create image --log-level=debug" on clean cluster and command successfully create image without any issues.
    2. For some reason if I delete the created ISO and try to create ISO image for second time on same cluster using "./openshift-install agent create image --log-level=debug ", throws error saying "FATAL failed to write asset (Agent Installer ISO) to disk: cannot generate ISO image due to configuration errors " 
    
    
Note : This issue because "openshift-install agent create image" generate a a file ".openshift_install_state.json". If this file already present seeing above mentioned error, For some reason if I try to generate ISO on same env.   

    Throws error "FATAL failed to write asset (Agent Installer ISO) to disk: cannot generate ISO image due to configuration errors " 

    It should create ISO image. 

    Expecting : Above issue need to be handled by updating Knowledge Center to remove the previous run ".openshift_install_state.json" OR "openshift-install agent create image" should overwrite or delete and create fresh one.
