Multus is refactored as a thick plugin, featuring 2 main components:
- a server listening to a unix domain socket, running in a pod
- a shim, a binary on the host that will send JSON requests built from
its environment / stdin values to the aforementioned server.
The pod where the multus daemon is running must share the host's PID
namespace.

thick, config: validate the cni config passed by the runtime
Without this patch, we're blindly trusting anything sent by the server.
This way, we assure the requests arriving at the multus controller are
valid before hand.

thick: model client / server config
Also add a new command line parameter on the multus controller, pointing
it to the server configuration.

multus: use args.args instead of an env variable
CNI is already filling the args structure; we should consume that
rather than rely on the environment variables.

To keep consistency between actual network and CNI result in cache,
update libcni cache when multus add/del default routes by
`default-route` network selection.
