Changing the name of model payment.acquirer to payment.provider and everything that it touches. It is technically incorrect to use the term "acquirer" for systems that only provide a service of payment. After this commit the model payment.acquirer and all related to it will be renamed to payment.provider.

to the user if they are redirected to this route with a POST request. Indeed, as the session

cookie is created without a `SameSite` attribute, some browsers that don't implement the

recommended default `SameSite=Lax` behavior will not include the cookie in the redirection
|
|
request from the payment provider to Odoo. As the redirection to the '/payment/status' page
|
|
will satisfy any specification of the `SameSite` attribute, the session of the user will be
|
|
retrieved and with it the transaction which will be immediately post-processed.
