Currently, the endpoints of headless services are retrieved
by querying pods using the pod selector of the service.
Instead, we now query for an Endpoints resource with the
same name as the Service object to get the endpoints for the
service. This is needed in order to support the
spec.publishNotReadyPods attribute of a service.

Using EC2 Instance Roles to provide Route 53 permissions is overly
permissive and dangerous.  Emphasize using alternatives such
as EKS IAM Roles for Service Accounts, kiam, or kube2iam that
limit access to the ExternalDNS pod.

Making sure the records are created depends on different settings. Add the section about debugging.
