Dalton Hubble 3d6a6d4adb Re-add Kubelet metadata service dependency on DigitalOcean 
* Restore the original special-casing of DigitalOcean Kubelets
* Fix node metadata InternalIP being set to the IP of the default
gateway on DigitalOcean nodes (regressed in v1.12.3)
* Reverts the "pretty" node names on DigitalOcean (worker-2 vs IP)
* Closes #424 (full details)

Dalton Hubble 721c847943 Set kube-apiserver kubelet preferred address types 
* Prefer InternalIP and ExternalIP over the node's hostname,
to match upstream behavior and kubeadm
* Previously, hostname-override was used to set node names
to internal IP's to work around some cloud providers not
resolving hostnames for instances (e.g. DO droplets)

Dalton Hubble 9b6113a058 Update Kubernetes from v1.11.3 to v1.12.1 
* Mount an empty dir for the controller-manager to work around
https://github.com/kubernetes/kubernetes/issues/68973
* Update coreos/pod-checkpointer to strip affinity from
checkpointed pod manifests. Kubernetes v1.12.0-rc.1 introduced
a default affinity that appears on checkpointed manifests; but
it prevented scheduling and checkpointed pods should not have an
affinity, they're run directly by the Kubelet on the local node

Dalton Hubble 6b08bde479 Use k8s.gcr.io instead of gcr.io/google_containers

Dalton Hubble 1b5caef4c1 Add Wants=rpc-statd.service to Kubelet 
* Mounting NFS exports as volumes from some NFS servers fails because
the kubelet isn't starting rpc-statd as expected. Describing pods

* Starting rpc-statd.service resolves the issue and all NFS mounts
seem to be working.

Dalton Hubble 097dcdf47e digital-ocean: Add kubelet hostname-override flag 
* Kubelets should register nodes via their private IPv4 address,
as provided by the metadata service from Digital Ocean
* By default, Kubelet exec's hostname to determine the name it should
use when registering with the apiserver. On Digital Ocean, the hostname
is not routeable by other instances. Digital Ocean does not run an
internal DNS service.
* Fixes issue where the apiserver can't reach the worker nodes. This
prevented kubectl logs and exec commands from working
