DomainID or DomainName validation is inconsistent

[digitalfredy]

Overview of the Issue

Using hashicorp/packer container with a HCL file that contains token:

• Setting domain_id (without domain_name) ask to remove it because is not required while using token
• If neither domain_name or domain_id is used then error asking for one of them
• If neither domain_name or domain_id is used but OS_DOMAIN_ID env var exported then is OK

Reproduction Steps

packer validate test.pkr.hcl

If domain_id = "default" + token = '...' then:

packer validate vault-raft.pkr.hcl
Error: 1 error(s) occurred:
* DomainID may not be provided when authenticating with a TokenID
  on vault-raft.pkr.hcl line 1:
  (source code not available)

If #domain_id = "default" = token = '...' then:

Error: 1 error(s) occurred:
* You must provide exactly one of DomainID or DomainName in a Scope with ProjectName
  on vault-raft.pkr.hcl line 1:
  (source code not available)

If #domain_id = "default" = token = '...' + export OS_DOMAIN_ID=default then:

The configuration is valid.

Plugin and Packer version

Simplified Packer Buildfile

test.pkr.hcl file:

source "openstack" "hello" {
  #domain_id                 = "default"
  token                     = "TheRealTokenWasHere"
  identity_endpoint         = "https://auth.cloud.ovh.net/v3"
  image_name                = "debian-hello-test"
  source_image_name         = "Debian 11"
  flavor                    = "s1-2"
  tenant_name               = "TheTenantNameWasHere"
  region                    = "GRA7"
  ssh_username              = "debian"
  networks                   = ["TheNetworkIdWasHere"]
}
build {
  sources = ["source.openstack.hello"]
  provisioner "shell" {
      execute_command = "sudo -S sh -c '{{ .Vars }} {{ .Path }}'"
      scripts         = fileset(".", "scripts/{install,secure}.sh")
  }
}

Operating system and Environment details

Docker image hashicorp/packer running in GitlabCI runner ignoring the entrypoint

Also tested in a Debian 11 laptop running the same Packer version.
