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.

adding a test case to test below case for RBD
* Create PVC and application
* Scale down application pod
* Create PVC-PVC ROX clone
* Try to create many pods that use the ROX PVC
* Try to write the data and verify only read
access.
