> {{-keepResults}} option is usually used to make it possible to rerun
> NNThroughputBenchmark with existing namespace state {{-useExisting}}. E.g.
> first generate files with {{create}} command and then run {{fileStatus}}
> command on generated files.
> NNThroughputBenchmark should call {{saveNamespace()}} when {{-keepResults}}
> option is specified. Otherwise NN startup takes a while since it needs to
> digest large edits file starting from the empty image.
