    QoS specs, allowing the specification of additional IO
    burst limits applied for each attached disk, individually.

    - quota:read_bytes_sec_max
    - quota:write_bytes_sec_max
    - quota:total_bytes_sec_max
    - quota:read_iops_sec_max
    - quota:write_iops_sec_max
    - quota:total_iops_sec_max
    - quota:size_iops_sec
