NEW|New endpoint paginated with limit and page

I've been added a new endpoint paginated for contract lines

[eldy]

In doc coment, you must add the type of var, for example:
@param int $id Id of contract

Corrected

[eldy]

Instead of a adding a new url endpoint, can you instead follow the same solution used for other api than need pagination:
Add the field
* @param int $limit Limit for list
* @param int $page Page number
* @param bool $pagination_data If this parameter is set to true the response will include pagination data. Default value is false. Page starts from 0*

Return old format when pagination_data is not set and return with pagination information when set.

See example into api that Get a list of orders. We should use the same way for api to get lines.
