Added Pagination while searching users.

[weierophinney]

Adding feature to search user with pagination?

• Why is the new feature needed? What purpose does it serve?

Most of Active directory has a limit of request users like 1k or 5k and if you need to get more users like 10k we need to use search and get users data with pagination.

• How will users use the new feature?

        $users = $this->zendLdap->multiPageSearch($filter, $baseDn, $scope, $fields);
        return $users;
