We add the flake8 configuration used so we ensure everyone uses the same. We remove the usage of __all__ for non public API. When possible, we rationalize the class name according to its __name__ and module. issue9082 review297061002
Sale Payment Module ################### The sale_payment module extends *Sale* to allow payments prior to the creation of any invoice. A field *Payments* is added on the sale which can be filled in quotation state. The sale can not be reset to draft or cancelled if there are no failed payment linked. The payment authorization of the full sale amount is used as confirmation of the sale. When an invoice from a sale is posted, its payments are used to pay invoice's *Lines to Pay*.
