DATACMNS-822 - Provide customizers for default pageable and sort resolvers.

Introduced dedicated callback interfaces to customize the HandlerMethodArgumentResolver instances registered by SpringDataWebConfiguration. This allows bean definition registration of those customizer interfaces instead of having to extend a configuration class.

Original pull request: #208.
