I just push a new version for PR 270

No more strange inheritance, Builders now use Configurator by composition.

I kept the distinction between configurator and builder to have different restriction between both.

BeanConfigurator duplicates all methods from BeanAttributesConfigurator, an alternative might be to compose them (BeanConfigurator consumes a BeanAttributesConfigurator)

Thanks for your review.

This PR is important to decide how we may manage other ticket like new version of SE bootstrap (CDI-568) or interceptor on producer (CDI-580)
