* Allow kube-dns to respond to DNS queries with a custom
suffix, instead of the default 'cluster.local'
* Useful when multiple clusters exist on the same local
network and wish to query services on one another

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
that are stuck creating shows rpc.statd is required for remote locking
* Starting rpc-statd.service resolves the issue and all NFS mounts
seem to be working.
* Recommended approach https://github.com/coreos/bugs/issues/2074

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
