ZF2-470: [RestClient] Rest client extends an unavailable Abstract class
RestClient implement an older class (Zend\Service\AbstractService) removed from the main zf2 repository (since commit <https://github.com/zendframework/zf2/…>). Didn't found the related compoment Zend\Service in zf2 (removed, u remember? :p) or in zendframework repositories.
AbstractService for RestClient is not really a mandatory abstract class but, I'm not really sure. I think that the good path is to have one ;)
