volumes; 2) to define common performance characteristics for volume; 3) to
change scheduler so that it can filter out unqualified back-ends.
Note: CLI commands for setting QOS are now included in the upstream Config Reference Guide.
The upstream CLI reference documents the following cinder qos-* commands:
