title: How can i filter data with JOLT Transform by several keys
body: <p>Am trying something  with Jolt transformation but struggling to get it to work.</p>
  
  <p>If I have an input like:</p>
  
  <pre><code> {"options": [
  {
    "id": "18031",
    "name": "sample",
    "archived": true,
    "released": true,
    "releaseDate": "2014-11-04",
    "userReleaseDate": "04 Nov 2014",
    "projectId": 13001
  },
  {
    "id": "231418",
    "description": "service_release",
    "name": "3.07.17",
    "archived": false,
    "flag_m": true,
    "releaseDate": "2017-07-03",
    "userReleaseDate": "03 Jul 2017",
    "projectId": 13001
  },
  {
    "id": "249700",
    "description": "service_release",
    "name": "service-09.02.18",
    "archived": false,
    "flag_m": false,
    "startDate": "2018-02-09",
    "userStartDate": "09 Feb 2018",
    "projectId": 13001
  }]}
  </code></pre>
  
  <p>I want output to be:</p>
  
  <pre><code> {
    "options" : [
     {
      "value" : "service-09.02.18",
      "key" : "service-09.02.18"
      }, 
      {
      "value" : "3.07.17",
      "key" : "3.07.17"  
      } 
     ]
    }
  </code></pre>
  
  <p>only for objects with flag_m=false and description=service_release</p>
  
  <p>Is this possible with Jolf transformation?</p>
