title: Symfony 2 config file and bundles configuration
body: <p>I'm developing a symfony2-based app and I'm using doctrine for db access. My entities are not in standard directory so I have to configure entities for each bundle in config file. Same goes for embeddables configuration and few custom data types. </p>
  
  <p>The problem is that config.yml is getting pretty huge. I'd like to split that config so all custom types and other bundle-related doctrine config would sit in bundle's directory. Is that possible with symfony2?</p>
