[Improvement]: cursor based navigation for GraphQL endpoints

[dkarlovi]

Improvement description

Pagination in GraphQL is meant to be cursor-based, which requires the pageInfo property.

Suggestion is to allow using arbitrary cursors (which are not int as currently created in schema, they should be string) and hopefully use Pimcore's cursor based pagination in Listing if implemented or implement an equivalent in DataHub if not.
