OpenPay payment gateway module for Odoo

This module is required for an ecommerce that's about to launch for selling fermented beverages like kombucha. Three payment methods are to be handled with this module: credit/debit cards, wiretransfers and cash in two or three modes: one time payment, subscription and in installments. The module needs to handle the webhooks that OpenPay has, to trigger actions on the server side of Odoo (This part doesn't necessarily has to be completley implemented, a skeleton of it would be ok).
