* Change the default kubeadm bootstrap token TTL from infinite to 24 hours. This is a breaking change. If you require the old behavior, use `kubeadm init --token-ttl 0` / `kubeadm token create --ttl 0`.

### Other notable changes

    * A new `k8s_external` plugin that allows external zones to point to Kubernetes in-cluster services.
    * CoreDNS now checks if a zone transfer is allowed. Also allow a TTL of 0 to avoid caching in the cache plugin.
    * TTL is also applied to negative responses (NXDOMAIN, etc).
