* If you want to test this out when an actual NFS export a good place
to start is by running the NFS server in a container:
docker run -d --name nfs --privileged cpuguy83/nfs-server /tmp
More detail can be found here:
https://github.com/cpuguy83/docker-nfs-server
This leaves `pkg/kubelet/server/server.go` looking a little ugly as there is an extra layer of "config" structs that isn't needed. This is left as a TODO for now.
Break up the monolithic volumes code in kubelet into very small individual
modules with a well-defined interface. Move them all into their own packages
and beef up testing along the way.
