title: Laravel validation with custom json respons
body: <p>Quick question. 
  Would it be possible to changes the JSON validation response of laravel?
  This is for a custom API that I am building in Laravel.</p>
  
  <p>Validation process</p>
  
  <pre><code>$validation = $this-&gt;validate( 
      $request, [
          'user_id' =&gt; 'required', 
      ]);
  </code></pre>
  
  <p>The response shows up like this in json</p>
  
  <pre><code>{
    "message": "The given data was invalid.",
    "errors": {
      "user_id": [
        "The user id field is required."
      ],
    }
  }
  </code></pre>
  
  <p>Preferable it would become something like this. </p>
  
  <pre><code>{
      "common:" [
          "status": "invalid",
          "message": "Param xxxx is required",
      ],
  }
  </code></pre>
  
  <p>What would be the best way to changes this? 
  Is it even possible?</p>
  
  <p>Thank you.</p>
