Incorrectly prepends io.k8s.api to resources where apiVersion has a single '.' in name

[gozer]

Terraform Version and Provider Version

Terraform v0.13.5

• provider registry.terraform.io/hashicorp/kubernetes-alpha v0.2.1

Kubernetes Version

Server Version: version.Info{Major:"1", Minor:"18+", GitVersion:"v1.18.9-eks-d1db3c", GitCommit:"d1db3c46e55f95d6a7d3e5578689371318f95ff9", GitTreeState:"clean", BuildDate:"2020-10-20T22:18:07Z", GoVersion:"go1.13.15", Compiler:"gc", Platform:"linux/amd64"}

Affected Resource(s)

• kubernetes_manifest

Terraform Configuration Files

resource "kubernetes_manifest" "crd-broken" {
  manifest = {
    apiVersion = "kci.rocks/v1alpha1"
    kind       = "DbInstance"

    metadata = {
      name = "test"
    }
    [...]
}

resource "kubernetes_manifest" "crd-working" {
  manifest = {
    apiVersion = "foo.kci.rocks/v1alpha1"
    kind       = "DbInstance"

    metadata = {
      name = "test"
    }
    [...]
}

Expected Behavior

Terraform should be able to plan and apply the resource

Actual Behavior

Error: rpc error: code = Unknown desc = failed to get resource type from OpenAPI (ID io.k8s.api.kci.v1alpha1.DbInstance): invalid type identifier

It seems that when dealing with an apiVersion that has a single '.' in the domain component, Terraform incorrectly prepends io.k8s.api and strips away the last part of the domain.

When the apiVersion is, for instance, foo.kci.rocks/v1alpha1 the issue dissapears

Steps to Reproduce

1. terraform plan

FWIW, I've observed incorrect prepend for an api version with multiple . in it.

resource "kubernetes_manifest" "target_group_binding" {
  provider = kubernetes-alpha

  for_each = { for k, v in
    # redacted
  }

  manifest = {
    "apiVersion" = "elbv2.k8s.aws/v1beta1"
    "kind"       = "TargetGroupBinding"
    "metadata" = {
      # redacted
    }
    "spec" = {
      # redacted
    }
  }

  lifecycle {
    create_before_destroy = true
  }
}

Resulting error

rpc error: code = Unknown desc = failed to get resource type from OpenAPI (ID io.k8s.api.elbv2.v1beta1.TargetGroupBinding): invalid type identifier
