Cannot create label for `upcloud_kubernetes_node_group` longer than 32 chars

[Pionerd]

As instructed by the UKS team (and as mentioned in the official k8s docs), I'm trying to set the node.kubernetes.io/exclude-from-external-load-balancers label on UKS nodes.

resource "upcloud_kubernetes_node_group" "example" {

  [...]

  labels = {
    managed-by   = "terraform"
    "node.kubernetes.io/exclude-from-external-load-balancers" = ""
  }
}

This throws the following error.

╷
│ Error: Invalid Attribute Value Length
│ 
│   with upcloud_kubernetes_node_group.example,
│   on example.tf line 20, in resource "upcloud_kubernetes_node_group" "example":
│   20:     "node.kubernetes.io/exclude-from-external-load-balancers" = ""
│   21:   }
│ 
│ Attribute labels["node.kubernetes.io/exclude-from-external-load-balancers"] string length must be between 2 and 32, got: 55

Label can be set manually (using kubectl) after node creation perfectly fine. Verified on latest version of the provider (v5.23.1).

Hello, thank you for reporting this! Fix on the TF provider side should be simple (#794), but seems that the node-group will be stuck in scaling-up state if there is label with len(key) > 32. Thus, we will need a fix on the API side as well to enable using the node.kubernetes.io/exclude-from-external-load-balancers label.
