> Currently, the agg service is exposed outside of the ps which is unnecessary.
> Thus, the task aims to privatize the agg service inside the ps. Concretly,
> the agg service will not run as a long-run thread. Instead, it will only be
> triggered inside the push method because it is at moment when workers push a
> new gradients should aggregate the gradients to update the model.
