This change introduces gopkg.in to allow everyone to use multus
code as library. Currently multus-cni uses version 'v3', hence
it hits go modules limitation, as #504 describes.
This change fix#504 with gopkg.in.
This change introduces kubelet client to get allocated device
information of a Pod from newly added Kubelet grpc service.
