Steps:
1. Get next available VMID from cluster
2. Clone template VM (full clone, new VMID)
3. Configure CPU, memory, and network interfaces
3. Configure CPU, memory, and dual NICs (mgmt + capture)
4. Verify snippet storage exists
5. Render cloud-init config to YAML and upload
6. Set Cloud-Init config references and SSH keys
7. Optionally resize root disk
8. Start the VM
9. Return VMID, name, node

8. Return VMID, name, node
Args:
name: new VM display name
template: template VMID/name to clone from
cpu: number of vCPUs
memory: RAM in MB
nics: list of NIC config dicts (bridge, vlan_tag/trunk_vlan_tags, dhcp flag)
mgmt_bridge: management bridge name
mgmt_vlan_tag: VLAN tag for mgmt NIC (None = untagged)
capture_bridge: packet capture bridge name (must be VLAN-aware)
capture_vlan_tags: list of VLAN IDs for capture NIC (trunk)
cloud_init_config: user-data dict (will be YAML-rendered)
ssh_public_keys: SSH public keys to inject
disk_resize_gb: resize root disk to this size (None = no resize)
timeout: max seconds for provisioning
