Incorrect interface name and default route in the node yaml when templating

[kastakhov]

Hi there,

I have a node with multiple interfaces, the first one (eno1) with IP assignment from DHCP and the second one (eno2) with static configuration, both have default gateway.

When I run talm template -e node_ip -n node_ip -t templates/controlplane.yaml -i > node.yaml, I got machine configuration with incorrect interface name, i.e.:

machine:
  network:
    interfaces:
      - interface: eno1eno2
        addresses:
          - node_eno2_ip
        routes:
          - network: 0.0.0.0/0
            gateway: node_eno1_gateway

Seems they are incorrectly handled in the _helpers.tpl for both generic and cozystack templates.
