CLOUDSTACK-9602: Improve resource limits comprehension in listResources (#1554)

Add resource type name in request and response for listResources API call.
This adds in the response a new attribute typename with the String value for the corresponding resource enum.

    {
      "capacitytotal": 0,
      "capacityused": 0,
      "percentused": "0",
      "type": 19,
      "typename": "gpu",
      "zoneid": "381d0a95-ed4a-4ad9-b41c-b97073c1a433",
      "zonename": "ch-dk-2"
    }
