resolve default storage class AWS > gp3-csi

[DanielOsypenko]

Resolve issue on FDF installations with AWS:

 The StorageCluster CR's storageDeviceSets[0].dataPVCTemplate does not specify a storageClassName. The operator can't determine which StorageClass to use for provisioning OSD PVCs,
  so it rejects the spec and enters Error phase.

  The cluster has two available StorageClasses: gp2-csi and gp3-csi (default). No Ceph resources, PVCs, or data pods have been created yet — the reconciliation fails before it gets
  that far.

Storageclass name should be set via StorageCluster with this manner:

 {
    "spec": {
      "storageDeviceSets": [{
        "name": "ocs-deviceset",
        "count": 1,
        "replica": 3,
        "portable": true,
        "dataPVCTemplate": {
          "spec": {
            "storageClassName": "gp3-csi",
            "accessModes": ["ReadWriteOnce"],
            "volumeMode": "Block",
            "resources": {
              "requests": {
                "storage": "100Gi"
              }
            }
          }
        }
      }]
    }
  }'
