example: add script to generate bios mbr raw disks

[mudler]

this needs refactoring and add to auroraboot, but it needs a cloud config of this format (the install block is relevant here, where it automatically power off after install):

#cloud-config

hostname: kairos-{{ trunc 4 .MachineID }}

# Automated install block
install:
  # Device for automated installs
  device: "auto"
  # Reboot after installation
  reboot: false
  # Power off after installation
  poweroff: true
  # Set to true to enable automated installations
  auto: true

## Login
users:
- name: "kairos"
  lock_passwd: true
  ssh_authorized_keys:
  - github:mudler

stages:
  boot:
  - name: "Repart image"
    layout:
      device:
        label: COS_PERSISTENT
      expand_partition:
        size: 0 # all space
    commands:
      # grow filesystem if not used 100%
      - |
         [[ "$(echo "$(df -h | grep COS_PERSISTENT)" | awk '{print $5}' | tr -d '%')" -ne 100 ]] && resize2fs /dev/disk/by-label/COS_PERSISTENT

at this point...do we move to packer to generate raw images instead? We can plug them both in CI and earthly pipelines easily and this seems like a convoluted way of doing so.

plus we got experience already .... xDDD

isn't packer even more complex at this point? this just works with a line of qemu and no configuration at all :->

we should at least add the needed cloud config as a comment (the relevant parts) in the script. Otherwise nobody will know what is needed to run the script.
