Description

Most resources export a locality ID (fr-par-1/xxxx-xxxx), when linking multiple resources altogether we should check that the localities match when needed.

For example, an instance should check that the ip zoned received is in the same zone.

Terraform snippet

resource scaleway_instance_ip ip {
  zone = "fr-par-2"
}

resource scaleway_instance_server server {
  type = "DEV1-S"
  zone = "fr-par-1"
  image = "ubuntu_jammy"
  ip_id = scaleway_instance_ip.ip.id
}

This snippet should fail on terraform plan
