Creating a QoS policy

The QoS policy groups the following performance capping levels: Max IOPS, Max MBPS, Burst, Burst factor and Burst duration. The QoS policy entity is assigned to an entity type (either a volume, or a pool).

Note: burst duration is available from the API only, and is hidden by CLI/GUI
