This allows an option `namespace` to be used instead of having Symfony generate the hash. If the option is not set, the original behaviour will occur.

While this code will execute on the current version, this change depends on https://github.com/doctrine/DoctrineBundle/pull/198 to fully work.

Drupal needs potentially to adapt the exception listener to add more information from the original request. (see http://drupal.org/node/2057607) so what about extracing some of the logic into a new method.
