Add systemd service that automatically bootstraps freshly deployed VMs
with their host-specific NixOS configuration from the flake repository.
Changes:
- hosts/template2/bootstrap.nix: New systemd oneshot service that:
- Runs after cloud-init completes (ensures hostname is set)
- Reads hostname from hostnamectl (set by cloud-init from Terraform)
- Checks network connectivity via HTTPS (curl)
- Runs nixos-rebuild boot with flake URL
- Reboots on success, fails gracefully with clear errors on failure
- hosts/template2/configuration.nix: Configure cloud-init datasource
- Changed from NoCloud to ConfigDrive (used by Proxmox)
- Allows cloud-init to receive config from Proxmox
- hosts/template2/default.nix: Import bootstrap.nix module
- terraform/vms.tf: Add cloud-init disk to VMs
- Configure disks.ide.ide2.cloudinit block
- Removed invalid cloudinit_cdrom_storage parameter
- Enables Proxmox to inject cloud-init configuration
- TODO.md: Mark Phase 3 as completed
This eliminates the manual nixos-rebuild step from the deployment workflow.
VMs now automatically pull and apply their configuration on first boot.

Implements Phase 1 of the OpenTofu deployment plan:
- Replace single-VM configuration with locals-based for_each pattern
- Support multiple VMs in single deployment
- Automatic DHCP vs static IP detection
- Configurable defaults with per-VM overrides
- Dynamic outputs for VM IPs and specifications
New files:
- outputs.tf: Dynamic outputs for deployed VMs
- vms.tf: VM definitions using locals.vms map
Updated files:
- variables.tf: Added default variables for VM configuration
- README.md: Comprehensive documentation and examples
Removed files:
- vm.tf: Replaced by new vms.tf (archived as vm.tf.old, then removed)
