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.

Errors like "pod nfs-820 does not have a host assigned" seem to get
reported when a Pod is not completely started yet, or was restarted
while trying to access it.

Set VolumeOptions.Pool parameter to empty for Snapshot-backed volumes.
This Pool parameter is optional and only used as 'pool-layout' parameter
during subvolume and subvolume clone create request in cephcsi
and not used for Snapshot-backed volume at all.
It is not saved anywhere for use in subsequent operations after create too.
Therefore, We can set it to empty and not error out.
