Capacity based QoS doc

Browse Source 
The Cinder Capacity based quality of service documentation does not
provide enough information to understand difference between
options to control capacity based quality of service.

These option can categorized into dynamic and minimum IOPS per volume
and dynamic and minimum bandwidth per volume.

There are currently 6 options to control capacity based quality of service
which values should be fairly self explanatory:
For dynamic IOPS per volume.
* `read_iops_sec_per_gb`
* `write_iops_sec_per_gb`
* `total_iops_sec_per_gb`
For dynamic bandwidth per volume.
* `read_bytes_sec_per_gb`
* `write_bytes_sec_per_gb`
* `total_bytes_sec_per_gb`

possible value. This can be useful in cases where a user creates a volume that
is very small and ends up with an unusable volume because of performance.
For minimum IOPS per volume.
* `read_iops_sec_per_gb_min`
