ilkermanap 3d4841f31c Initial commit: MAAS-deployable Proxmox VE images with cluster automation ...

Builds a Proxmox VE image that MAAS can deploy to bare metal, plus first-boot
automation that configures the node and joins it to a Proxmox cluster with no
manual steps.

The image starts from the official Debian cloud image and installs proxmox-ve
on top of it, rather than capturing a raw disk from the Proxmox ISO. That keeps
MAAS in control of partitioning, networking, SSH keys and cloud-init, and makes
moving between Proxmox releases a variable change instead of a rewrite.

Contents:

  * Makefile driving the whole flow: build, verify, preseed, upload
  * customize-proxmox.sh, run inside the Packer build VM, which layers Proxmox
    onto the Debian cloud image and resets the pmxcfs node identity so one image
    can produce many nodes
  * pve-maas-init, a first-boot state machine covering /etc/hosts, node-unique
    identifiers, the root password, vmbr0 conversion, cluster create/join and
    the local-lvm thin pool; each stage is resumable across reboots
  * curtin-hooks, which stops curtin installing a kernel over APT and pins
    interface names by MAC so they match what MAAS recorded at commissioning
  * a MAAS curtin preseed template and cloud-init examples
  * deploy-cluster.sh, which builds a whole cluster through the MAAS API
  * verify-image.sh, 22 static checks on the produced tarball

Cluster identity lives entirely in deploy-time cloud-init user-data, so a single
image and preseed can build any number of independent clusters.

Verified end to end against MAAS 3.7.2: proxmox-ve 9.2.0 / pve-manager 9.2.11 /
kernel 7.0.14-15-pve, deployed to two machines that formed a quorate cluster with
local-lvm on both, with no manual intervention.

The README documents four failure modes found along the way that all fail
silently: curtin rejecting "kernel: null", pvenetcommit overwriting the network
configuration at boot, interface renaming leaving the link down, and a systemd
ordering cycle that made systemd delete the service's start job.
