Capacity based options might be used in conjunction with basic options,
like `*_sec_max`, in order to set upper limits for volumes. This may be useful
for large volumes, which may consume all storage performance.

For example, in order to create a QoS with 30 IOPs total writes per GB and
a throughput of 1MB per GB, you might use the Cinder client in the following
