Add a findAll that takes a Pageable and returns a Slice instead of a Page

[simasch]

The PagingAndSortingRepository has a Page<T> findAll(Pageable pageable) method.

The problem is that returning a Page will result in a count and a select statement.

The same problem is present in JpaSpecificationExecutor. So it would be awesome to have this covered as well.

So, should we define findAll that returns a Slice instead?

One option would be to avoid extending any base interface and create additional interfaces that provide this extra functionality:

• PagingBaseJpaRepository
• SlicingBaseJpaRepository

+1 for the additional interfaces
