Input schema for POST(Create) of Storage Pool/StorageGroup

Venkatesh Periyasamy: On StoragePool creation, the idea is to specify one or more ClassOfService entities. That and Capacity data structure specifies the desired amount of storage for Data, Metadata and Snapshots. Also whether storage is to be allocated thin or not. The choice of specific underlying storage is intended to be left to the implementation using that info. You could go farther and specify values for the CapacitySources property, but that is NOT the swordfish intention, since the goal is to push decisions about how the results are provided is intended to be pushed down to the implementation.

On StorageGroup creation, there is a change queued up that will change the resource collections into simple collections. We've learned that the use of resource collections for these properties was overkill. The intention is that you can POST to create the StorageGroup as a whole.
