Registered by
Simon Dodsley
Add support for back-end Quality of Service settings.
Use QoS specs that have been associated to a volume_type.
Settings supported are maxIOPS and maxBW
maxIOPS is an integer between 100 and 100000000
MaxBWS is a value between 1MB/s and 512GB/s expressed as an integernumber of MB/s
(1 MB/s = 1 and 512GB/s = 524288)
QoS settings are applied to volumes in the following cases:
1. New volume creation
2. Volume retyping
3. Manage existing volume
4. Create volume from snapshot
5. Cloing volume
