This writable object lets a management station clear the counters stored in this archived QoS shaper history bin. It matters because it lets an admin explicitly discard a stale or corrupted historical record instead of leaving it to be overwritten naturally, useful when cleaning up after a known bad measurement period. For example, if a history bin was captured during a device reboot and contains meaningless partial counts, an admin would write to cmQosShaperHistoryAction to clear that specific bin.
