Title: [DoctrineBridge] Separated ORM specific stuff from the generic form code

I separated the choice list and the form type into 2 classes each. this way, other Doctrine bundles can create another implementation extending from the abstract classes.
If you find a way to get rid of the abstract choice list (needed because we use the unit of work), it would be even cleaner
