[Security] moved Security classes out of DoctrineBundle, cleaned-up SecurityExtension accordingly

Note that this commit removes the built-in support for MongoDB user providers.
This code can be moved back in once there is a stable release for MongoDB, but
for now you have to set-up that user provider just like you would set-up any
custom user provider:

    security:
         providers:
             document_provider:
                 id: my.mongo.provider
