Pagination: Add package to manage pagination without using gorm

Pagination needs to be added to different services, but the current implementation heavily relies on gorm.

This MR adds a new pagination package that manages pagination without depending on gorm. This package also include a set of unit and integration tests for using pagination with HTTP, that the previous implementation didn't have.
