It might be good to put RestartPolicy structure to CreateContainerRequest / UpdateContainerRequest:

message RestartPolicy {
	RestartCondition condition = 1; // "none", "on-failure", (and "any" if needed)
        Duration Delay = 2;
        int64 MaxAttempts = 3;
}

I guess this is useful for linuxkit, cc linuxkit maintainers @ijc25 @justincormack @riyazdf @rneugeba
