This makes it a bit simpler to remove this interface for v2 plugins and not break external projects (libnetwork and swarmkit). Note that before we remove the `Client()` interface from `CompatPlugin` libnetwork and swarmkit must be updated to explicitly check for the v1 client interface as is done int his PR. This is just a minor tweak that I realized is needed after trying to implement the needed changes on libnetwork. Signed-off-by: Brian Goff <cpuguy83@gmail.com>
