cproudlock dd2fec5a41 Blancco PXE boot via Ubuntu kernel switch_root ...

Blancco's own kernel freezes on Dell Precision towers during PXE boot.
Workaround: boot Ubuntu kernel via GRUB chainload, download Blancco's
666MB squashfs rootfs + 132MB kernel modules over HTTP, mount overlay
filesystem, and switch_root into Blancco's userspace.

- Add blancco-init.sh: custom initramfs init script for switch_root approach
- Add blancco-preferences.xml: pre-configured with network share for reports
- Update playbook: build initramfs, deploy Ubuntu kernel/modules, config
- Update prepare-boot-tools.sh: add HTTP modules to GRUB EFI build
- Add UEFI HTTP Boot support to dnsmasq config
- iPXE menu chains to grubx64.efi (replaces sanboot of ISO)
