title: How apply pagination in reactive Spring Data?
body: <p>In Spring Data, we have <code>PagingAndSortingRepository</code> which inherits from <code>CrudRepository</code>. In reactive Spring Data, we only have 
  <code>ReactiveSortingRepository</code> which inherits from <code>ReactiveCrudRepository</code>.
  How could we make pagination in a reactive way ?
  Will we able to make this in future with <code>ReactivePagingAndSortingRepository</code> for instance?</p>
