QoS specs is standalone entity that can be associated/disassociated with volume types (one to many relation). Adjacency list relationship pattern is used in this model in order to represent following hierarchical data with in flat table, e.g, following structure:

qos-specs-1  'Rate-Limit'
     |
     +------>  consumer = 'front-end'
     +------>  total_bytes_sec = 1048576
     +------>  total_iops_sec = 500

qos-specs-2  'QoS_Level1'
     |
     +------>  consumer = 'back-end'
     +------>  max-iops =  1000
     +------>  min-iops = 200

is represented by:

  id       specs_id       key                  value
------     --------   -------------            -----
