Remove obsolete bootstrap script and update example script for clarity</message>

<message>Delete the existing bootstrap.sh script used for cloud-init first boot, as it is no longer needed. Update the bootstrap.sh.example script to provide clearer instructions for users on how to customize and deploy their own bootstrap script, ensuring better guidance for cloud-init integration. These changes streamline the provisioning process and enhance user experience.
