Update a payload format to be compatible to OIC spec in easysetup

Update a payload format to be compatible to OIC spec in easysetup

1. In a response for get/post request with batch interface,
   "rep" keyword should be included for containing child resource's properties
   for each child resource.
2. Provisioning resource is a collection resource so it should have
   a "oic.wk.col" resource type.
3. "links" property for baseline and linklist interfaces should include a
   "p"(i.e. policy) property.

e.g. response for baseline:
{
  "rt":[
    "oic.wk.prov",
    "oic.wk.col"
  ],
  "if":[
    "oic.if.baseline",
    "oic.if.ll",
    "oic.if.b"
  ],
  "ps":0,
  "lec":0,
  "links":[
    {
      "href":"/WiFiProvisioningResURI",
      "rt":[
        "oic.wk.wifi"
      ],
      "if":[
        "oic.if.baseline"
      ],
      "p":{
        "bm":3
      }
    },
    {
      "href":"/DevConfProvisioningResURI",
      "rt":[
        "oic.wk.devconf"
      ],
      "if":[
        "oic.if.baseline"
      ],
      "p":{
        "bm":3
      }
    },
    {
      "href":"/CloudServerProvisioningResURI",
      "rt":[
        "oic.wk.cloudserver"
      ],
      "if":[
        "oic.if.baseline"
      ],
      "p":{
        "bm":3
      }
    }
  ]
}

e.g. response for linklist:
{
  "links":[
    {
      "href":"/WiFiProvisioningResURI",
      "rt":[
        "oic.wk.wifi"
      ],
      "if":[
        "oic.if.baseline"
      ],
      "p":{
        "bm":3
      }
    },
    {
      "href":"/DevConfProvisioningResURI",
      "rt":[
        "oic.wk.devconf"
      ],
      "if":[
        "oic.if.baseline"
      ],
      "p":{
        "bm":3
      }
    },
    {
      "href":"/CloudServerProvisioningResURI",
      "rt":[
        "oic.wk.cloudserver"
      ],
      "if":[
        "oic.if.baseline"
      ],
      "p":{
        "bm":3
      }
    }
  ]
}

e.g. response for batch:
[
  {
    "href":"/ProvisioningResURI",
    "rep":{
      "if":[
        "oic.if.baseline",
        "oic.if.ll",
        "oic.if.b"
      ],
      "rt":[
        "oic.wk.prov",
        "oic.wk.col"
      ],
      "ps":0,
      "lec":0
    }
  },
  {
    "href":"/WiFiProvisioningResURI",
    "rep":{
      "if":[
        "oic.if.baseline"
      ],
      "rt":[
        "oic.wk.wifi"
      ],
      "swmt":[
        2,
        3,
        4
      ],
      "swf":1,
      "tnn":"",
      "cd":"",
      "wat":0,
      "wet":0
    }
  },
  {
    "href":"/CloudServerProvisioningResURI",
    "rep":{
      "if":[
        "oic.if.baseline"
      ],
      "rt":[
        "oic.wk.cloudserver"
      ],
      "ac":"",
      "apn":"",
      "cis":""
    }
  },
  {
    "href":"/DevConfProvisioningResURI",
    "rep":{
      "if":[
        "oic.if.baseline"
      ],
      "rt":[
        "oic.wk.devconf"
      ],
      "dn":"Test Device",
