 Description: Site-wide data resource limits and current usage, including storage, data item counts, and data collection counts.
       - name: storageLimitInBytes  | type: string | description: Maximum storage allowed for all native collections combined, in bytes.  Storage usage is shared between the live and sandbox environments. For example, with a limit of 1 GB, the live environment could use 700 MB and the sandbox 300 MB before the limit is reached.  When this limit is reached, writes to collections fail.
           - name: value  | type: string | description: 
       - name: itemCountLimit  | type: string | description: Maximum number of data items allowed per environment.  This limit applies separately to the live and sandbox environments. For example, with a limit of 1,000, both the live and sandbox environments can each contain 1,000 items independently.  When this limit is reached in an environment, writes to collections in that environment fail.
       - name: collectionCountLimit  | type: number | description: Maximum number of native data collections allowed.
