Introduce CursorPager
What does this MR do?
For https://gitlab.com/gitlab-org/gitlab/-/issues/331493, as discussed in !68346 (comment 652611098)
This MR introduces the CursorPager class which helps to keyset paginate a given relation and also applies the header to the request that generates the link to the next page. The CursorPager wraps the generic keyset pagination library. We plan to use the CursorPager class to implement keyset pagination for various REST API endpoints.
No changelog added as this MR only introduces the service, but does not use it anywhere.
