Implement volumes as plugins. 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.

Add flocker volume plugin Flocker [1] is an open-source container data volume manager for Dockerized applications. This PR adds a volume plugin for Flocker. The plugin interfaces the Flocker Control Service REST API [2] to attachment attach the volume to the pod. Each kubelet host should run Flocker agents (Container Agent and Dataset Agent). The kubelet will also require environment variables that contain the host and port of the Flocker Control Service. (see Flocker architecture [3] for more). - `FLOCKER_CONTROL_SERVICE_HOST` - `FLOCKER_CONTROL_SERVICE_PORT` The contribution introduces a new 'flocker' volume type to the API with fields: - `datasetName`: which indicates the name of the dataset in Flocker added to metadata; - `size`: a human-readable number that indicates the maximum size of the requested dataset. Full documentation can be found docs/user-guide/volumes.md and examples can be found at the examples/ folder [1] https://clusterhq.com/flocker/introduction/ [2] https://docs.clusterhq.com/en/1.3.1/reference/api.html [3] https://docs.clusterhq.com/en/1.3.1/concepts/architecture.html

Covert the kubelet binary to hyperkube. 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.
