Moby imports Swarmkit; Swarmkit no longer imports Moby. In order to accomplish this feat, Swarmkit has introduced a new plugin.Getter interface so it could stop importing our pkg/plugingetter package. This new interface is not entirely compatible with our plugingetter.PluginGetter interface, necessitating a thin adapter. Swarmkit had to jettison the CNM network allocator to stop having to import libnetwork as the cnmallocator package is deeply tied to libnetwork. Move the CNM network allocator into libnetwork, where it belongs. The package had a short an uninteresting Git history in the Swarmkit repository so no effort was made to retain history.
