Migtating user interface from smart grid to sched bpf, which allows
users to set SCHED_GRID_QOS_TASK_LEVEL through:

        /proc/${pid}/task/${pid}/tag

interface. Although arbitrary integer value could be assigned to
, currnetly we clamp the value of SCHED_GRID_QOS_TASK_LEVEL
to 0-7, which maintains consistency.
