Paginate `Users` list

Motivation

In case in an instance there are many users (for example a few hundreds) in the current state G3W-ADMIN fetches the entire list of users and then deletes Datatable in the pagination. This solution is good for cases where there is a limited number of users, but in the case of a large number it would be more appropriate to have a client-server paging system.

Suggested solution

Replace the classic user list system based on total user upload to a REST API based system for Datatable, where the user data list is retrieved via Ajax calls.
