Known issues

• Currently, OpenPai start user's job using hostNetwork and leverge docker stats to generate job's running metrics including network usage. This will render 0 network usage in job/task metrics page, because docker stats will return 0 network usage if container uses hostNetwork. We will fix this issue in future release.
