Issue MESOS-4358: Expose net_cls network handles in agent's state endpoint
We need to expose net_cls network handles, associated with containers, to operators and network utilities that would use these network handles to enforce network policy. In order to achieve the above we need to add a new field in the `NetworkInfo` protobuf (say NetHandles) and update this field when a container gets assigned to a net_cls cgroup. The `ContainerStatus` protobuf already has the `NetworkInfo` protobuf as a nested message, and the `ContainerStatus` itself is exposed to operators as part of TaskInfo (for tasks associated with the container) in an agent's state.json.
