title: Write file with camel and set chmod
body: <p>The camel FTP component allows to <strong>set chmod</strong> property (see <a href="http://camel.apache.org/ftp2.html" rel="nofollow">Apache Camel: FTP2</a>) on stored files.
  Is there a way to do the same with the <strong>camel file component</strong> ?</p>
  
  <p>Something like <code>from("somewhere").to("file:foo.txt?chmod=666")</code>.</p>
  
  <p>If not, do you know a <em>nice way</em> to do that with camel ?</p>
