Add support to the new id entity generation preferences in Doctrine ORM 3.0

[TeLiXj]

Feature Request

A few months ago, the default AUTO setting in the generated value attribute was deprecated (#[ORM\GeneratedValue]) to force one to be chosen. For now, only PostgreSQL is affected and you can now configure it with a new global setting identityGenerationPreferences.
