HOM-481: Optional dedicated etcd data disk + data disk I/O tuning

What

  • Adds optional control_plane_data_disk_* variables to the talos-cluster module so etcd can be moved to a dedicated disk in a future maintenance window.
  • Adds data_disk_cache / data_disk_iothread variables to the proxmox-vm module.
  • Defaults keep the change safe: CP data disk is disabled (null) unless explicitly sized.

Why

Supports the HOM-481 etcd I/O remediation by giving the platform a path to isolate etcd WAL/snapshots from the boot disk.

Safety

  • No disk is provisioned or formatted unless control_plane_data_disk_gb is set.
  • A runbook covers the offline migration required before enabling the disk on an existing node.

Rollback

  • Revert this PR + re-apply Terraform; no storage layout changes are performed by this change.
