Enhance provisioning documentation and scripts for improved network boot and DNS management</message>

<message>Add new documentation files for device DNS management via DHCP and dnsmasq configuration. Update cloud-init scripts to ensure proper handling of /etc/resolv.conf and DNS settings, allowing for seamless integration with file.server. Modify existing scripts to support dynamic LAN subnet configuration and improve overall network boot functionality. These changes enhance user experience and streamline the setup process for the CM4 eMMC provisioning service.
