Query Option "interval" is Broken

[HyunsungJo]

Problem

The "interval" option doesn't seem to work on secondary indices.

Steps to Reproduce Issue

1. Create service.

   curl -XPOST localhost:9000/graphs/createService -H 'Content-Type: Application/json' -d '
   {
    "serviceName": "interval",
    "hTableName": "interval-dev"
   }
   '

2. Create label with more than multiple indices.

   curl -XPOST localhost:9000/graphs/createLabel -H 'Content-Type: Application/json' -d '
   {
    "label": "interval_test",
    "srcServiceName": "interval",
    "srcColumnName": "ad_id",
    "srcColumnType": "string",
    "tgtServiceName": "interval",
    "tgtColumnName": "url",
    "tgtColumnType": "string",
   "isDirected": "true",
   "indices": [
      {
          "name": "_PK",
          "propNames": [
              "_timestamp"
          ]
      },
      {
          "name": "IDX_ACTION_TYPE",
          "propNames": [
              "actionType",
              "_timestamp"
          ]
      }
   ],
   "props": [
      {
          "name": "serviceName",
          "defaultValue": "",
          "dataType": "string"
      },
      {
          "name": "actionType",
          "defaultValue": "",
          "dataType": "string"
      }
   ],
   "consistencyLevel": "strong"
   }
   '

3. Insert test data.

   curl -XPOST -H 'Content-Type: application/json' localhost:9000/graphs/edges/insert -d '
   [
     {
         "from": "jojo",
         "to": "www.kakaocorp.com",
         "label": "interval_test",
         "props": {"serviceName": "talk-scrap", "actionType": "share"},
         "timestamp": 1433495457557
     }
   ]
   '

4. Query with interval on primary index. => This works! (edge returned)

   curl -XPOST localhost:9000/graphs/getEdges -H 'Content-type: Application/json' -d '
   {
      "srcVertices": [
          {
              "serviceName": "interval",
              "columnName": "ad_id",
              "id": "jojo"
          }
      ],
      "steps": [
          {
              "step": [
                  {
                      "label": "interval_test",
                      "index": "_PK",
                      "interval": {
                          "from": [
                              {
                                  "_timestamp": 1433495457556
                              }
                          ],
                          "to": [
                              {
                                  "_timestamp": 1433495457558
                              }
                          ]
                      }
                  }
              ]
          }
      ]
   }
   '

5. Query with interval on secondary index. => Doesn't work!! (empty result..)

   curl -XPOST localhost:9000/graphs/getEdges -H 'Content-type: Application/json' -d '
   {
      "srcVertices": [
          {
              "serviceName": "interval",
              "columnName": "ad_id",
              "id": "jojo"
          }
      ],
      "steps": [
          {
              "step": [
                  {
                      "label": "interval_test",
                      "index": "IDX_ACTION_TYPE",
                      "interval": {
                          "from": [
                              {
                                  "actionType": "share"
                              }
                          ],
                          "to": [
                              {
                                  "actionType": "share"
                              }
                          ]
                      }
                  }
              ]
          }
      ]
   }
   '

   Cause of Issue

The function interval() in QueryParam.scala uses labelOrderSeq witch is currently not set at time of function call. In function parseQueryParam() of RequestParser.scala, .interval(interval) should come after .labelOrderSeq(indexSeq).
