title: Email confirmation on FOSUserBundle Profile Edit
body: <p>I would like to activate the email confirmation on FOSUserBundle <strong>/profile/edit</strong></p>
  
  <p>In <strong>/profile/edit</strong> you are already logged in and you can edit the username or the email address entering the current password.
  Now I would like to send a confirmation email if the user edit the email address :)</p>
  
  <p>In the <strong>FOSUserBundle Configuration Reference</strong> I haven't found a setting to do this...
  <a href="https://github.com/FriendsOfSymfony/FOSUserBundle/blob/master/Resources/doc/configuration_reference.md" rel="noreferrer">https://github.com/FriendsOfSymfony/FOSUserBundle/blob/master/Resources/doc/configuration_reference.md</a></p>
  
  <p>These are my current settings:</p>
  
  <pre><code>fos_user:
    db_driver: orm
    firewall_name: main
    user_class: Acme\CoreBundle\Entity\User
    registration:
      confirmation: { enabled: true }
    from_email:
      address: noreply@%domain%
      sender_name: %site_name% Staff
    resetting:
      token_ttl: %reset_password_ttl%
  </code></pre>
  
  <p>Someone can help me?</p>
