enable the ability to change the kubernetes API version from vars

[jcalles]

Describe the Feature

Im using Atlantis to deploy and change my EKS cluster and whenI've tried to use this var: kube_exec_auth_enabled = true terraform fails as shown:

Error: Failed to configure client: exec plugin: invalid apiVersion "client.authentication.k8s.io/v1alpha1"

Error: Failed to configure client: exec plugin: invalid apiVersion "client.authentication.k8s.io/v1betha1"

I have added this code in variables.tf:

variable "k8s_provider_api_version" {
default = "client.authentication.k8s.io/v1"
}

and this in auth.tf

dynamic "exec" {
    for_each = local.kube_exec_auth_enabled ? ["exec"] : []
    content {
      #api_version = "client.authentication.k8s.io/v1alpha1"
      api_version = var.k8s_provider_api_version

Expected Behavior

No changes. Infrastructure is up-to-date.

This means that Terraform did not detect any differences between your
configuration and real physical resources that exist. As a result, no
actions need to be performed.

Use Case

to run terraform in CI/CD pipelines
