title: lodash - project/transform object into key value array
body: <p>I'm about to use <code>forOwn</code> to iterate through an object's properties and create an array manually and can't helping thinking there's a oneliner already available to do it.</p>
  
  <pre><code>{ 
    prop1 : "value",
    prop2: { sub:1}
  }
  </code></pre>
  
  <p>to:</p>
  
  <pre><code>[ 
     {key: "prop1", value: "value"},
     {key: "prop2", value: {sub:1}}
  ]
  </code></pre>
  
  <p>Thanks</p>
