Network issues

[heroinedor]

Following the first experimentation of connexion with CapGemini network, here are some points to investigate :

• [ ] is it possible to avoid the creation of private networks, and deploy our infrastructure on the Capgemini's existing network ?
• [x] is it possible to fix the vlan_id of a private network ?
• [x] is it possible to avoid the creation of the router ?

• [x] update env var in develop env
• [ ] update env var in preprod env

Modif reverted. Prod fork will use

  value_specs = {
    "provider:network_type" = "vlan"
    "provider:segmentation_id" = var.van_id
  }
