Yite Gu 4774a82e88 rbd: support QoS based on capacity for rbd volume
1. QoS provides settings for rbd volume read/write iops
   and read/write bandwidth.
2. All QoS parameters are placed in the SC,
   send QoS parameters from SC to Cephcsi through PVC create request.
3. We need provide QoS parameters in the SC as below:
   - BaseReadIops
   - BaseWriteIops
   - BaseReadBytesPerSecond
   - BaseWriteBytesPerSecond
   - ReadIopsPerGB
   - WriteIopsPerGB
   - ReadBpsPerGB
   - WriteBpsPerGB
   - BaseVolSizeBytes
   There are 4 base qos parameters among them, when users apply for
   a volume capacity equal to or less than BaseVolSizebytes, use base
   qos limit. For the portion of capacity exceeding BaseVolSizebytes,
   QoS will be increased in steps set per GB. If the step size parameter
   per GB is not provided, only base QoS limit will be used and not associated
   with capacity size.
4. If PVC has resize request, adjust the QoS limit
   according to the QoS parameters after resizing.
