instead of adding zone wide primary storage in the cluster block,

added it in the zone block.
CLOUDSTACK-8229
Testing: tested with KVM and zone deployment was fine.

In the config file, zone wide primary storage details looks like this:
  "primaryStorages": [
        {
          "url": "nfs://10.147.28.7/export/home/talluri/primary1",
          "XRT_PriStorageType": "NFS",
          "name": "XenRT-Zone-0-Pod-0-Cluster-0-Primary-Store-0",
          "hypervisor": "KVM",
          "scope" : "zone"
        }
      ],
