title: Access controller plugins in mapper in zf2
body: <p>I am creating an application in zf2.</p>
  
  <p>I have a Plugin (MyModule\Controller\Plugin\MyPlugin) that I can call in my controller without any problem.</p>
  
  <p>I would like to be able to call it from a mapper (like it was possible in zf1 doing getStaticHelper().
  I found that it is possible to get it in the view by doing Zend_Controller_Front::getInstance() and then call the plugin but this doesn't work in the mapper.</p>
  
  <p>Is that possible?
  Thanks!</p>
