Support for Configurable Dynamic ks.cfg Templates

[QYG2297248353]

The unattended installation file (kickstart file) can be fetched via a custom service. Based on information such as the machine's MAC address, the system dynamically generates an appropriate configuration file to perform the OS installation.

{
    "control": [
        {
            "iso": "/ISO/AlmaLinux-9.iso",
            "kernel_param": "inst.ks=http://10.0.0.1:8000/ks.php"
        }
    ]
}

The boot script should support specifying a directory and automatically retrieve the corresponding configuration file from that directory.
