Camunda delete all variables on process
<p>In the camunda rest api is there a way to delete all the process instance variables in one go.</p>

<p>I thought I read some documentation that said you could do it using...</p>

<pre><code>DELETE http://localhost:8080/contextRoot/rest/engine/default/process-instance/{id}/variables
</code></pre>

<p>But when I try that I get a ...</p>

<pre><code>{
  "timestamp": 1479705176075,
  "status": 405,
  "error": "Method Not Allowed",
  "message": "Method Not Allowed",
  "path": "/contextRoot/rest/engine/default/process-instance/14/variables"
}
</code></pre>

<p>If I add a variable id I am able to delete one by one but that's not what I'm after.</p>

<p>thanks</p>
