Remove providers (#670)

* Move all but mock provider out of tree

These have all been moved to repos under github.com/virtual-kubelet.

* Introduce a providers.Store

This essentially moves the the old register/ handling into a first class
object that can be controlled from the CLI rather than through build
tags deep in the code.

This actually would have made it a bit easier to build the provider
repos and makes the cmd/ code more re-usable.
