        Add a new hook: 92-crashkernel.install
    
        To track and manage kernel's crashkernel usage by kernel version,
        each kernel package will include a crashkernel.default containing the
        default `crashkernel=` value of that kernel. So we can use a hook to
        update the kernel cmdline of new installed kernel accordingly.
    
        Put it after all other grub boot loader setup hooks, so it can simply
        call grubby to modify the kernel cmdline.
