   Addresses: kubernetes/enhancements#88
   
   This commit starts breaking the controller manager into two pieces, namely,
   
   1. cloudprovider dependent piece
   2. coudprovider agnostic piece
   
   the controller manager has the following control loops -
   
      - nodeController
      - volumeController
      - routeController
      - serviceController
      - replicationController
      - endpointController
      - resourcequotacontroller
      - namespacecontroller
      - deploymentController etc..
   
   among the above controller loops,
   
      - nodeController
      - volumeController
      - routeController
      - serviceController
   
   are cloud provider dependent. As kubernetes has evolved tremendously, it has become difficult
   for different cloudproviders (currently 8), to make changes and iterate quickly. Moreover, the
   cloudproviders are constrained by the kubernetes build/release lifecycle. This commit is the first
   step in moving towards a kubernetes code base where cloud providers specific code will move out of
   the core repository, and will be maintained by the cloud providers themselves.
   
   Finally, along with the controller-manager, the kubelet also has cloud-provider specific code, and that will
   be addressed in a different commit/issue.
