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`
