Panic when converting ReplicationController

[Rafael Fonseca]

Latest release (0.2.8) crashes when attempting to convert the following YAML:

apiVersion: v1
kind: Service
metadata:
  name: echoheaders
  namespace: platform
  labels:
    app: echoheaders
spec:
  type: NodePort
  ports:
    - port: 80
      targetPort: 8080
      protocol: TCP
      name: http
  selector:
    app: echoheaders
---
apiVersion: v1
kind: ReplicationController
metadata:
  name: echoheaders
  namespace: platform
spec:
  replicas: 1
  template:
    metadata:
      labels:
        app: echoheaders
    spec:
      containers:
        - name: echoheaders
          image: k8s.gcr.io/echoserver:1.10
          ports:
            - containerPort: 8080

Output

resource "kubernetes_service" "echoheaders" {
  metadata {
    name      = "echoheaders"
    namespace = "platform"
    labels    = { app = "echoheaders" }
  }
  spec {
    port {
      name        = "http"
      protocol    = "TCP"
      port        = 80
      target_port = "8080"
    }
    selector = { app = "echoheaders" }
    type     = "NodePort"
  }
}

Thanks for the details, I think I can see what's causing this issue.
