SolidFire volume creation from clone should allow setting of QoS

[dutchiechris]

If you create a clone volume using docker volume create --driver netapp --name volGoldClone -o from=volGold the QoS settings are inherited/reused from the parent. If you pass a specific option like -o type=dev this is ignored. Especially when making dev/test clones of production a different QoS limit is desired. If nDVP would allow specifying QoS settings to clones it would avoid other external post scripts that are currently needed.

Thanks dutchiechris, pretty easy to add in; I'll get it pushed internally and it should pop out in the next release.
