Add a pagination index settings resource to manage customization of the maximum number of reachable documents during the search at the index level.

• Expose pagination object on /indexes/:index_uid/settings endpoints.
• Add GET/PATCH/DELETE - /indexes/:index_uid/settings/pagination endpoints.

The pagination object definition is made of the following properties:

• maxTotalHits type (int)

More information about what each field does could be checked in the spec.

Check the other customization methods for reference like: synonyms, searchableAttributes, filterableAttributes.

TODO:

• Add the new methods to customize pagination
  • GET /indexes/:index_uid/settings/pagination
  • PATCH /indexes/:index_uid/settings/pagination
  • DELETE /indexes/:index_uid/settings/pagination
• Add tests
