I'm not a fan of having multiple interfaces to do one thing if it can
be avoided.  Presumably the argument for the netlink API is the
container folks don't want to have to mount /proc inside containers
which are going to host nested orchestrators?  Can you reasonably run
a fully fledged orchestrator without a valid /proc?
