Add support for keyset scrolling

[mp911de]

Based on spring-projects/spring-data-commons#2151, we want to add means to consume a query result set through a scroll API to be able to resume querying at a later stage. We want to introduce keyset-based pagination which allows using keysets to reconstruct a scroll position for subsequent queries.

Tasks:

• Add support for Keyset- and Offset-based cursor scrolling #4317
• Add support for reverse scrolling #4325
• Add support for keyset extraction of nested property paths #4326
