Notification handling in some acquirers presents a subset of the
following issues:
1. The signature of synchronous notifications (redirect payloads) is not
checked. (Alipay, Authorize, Buckaroo, Mollie, PayU money, PayULatam)
2. When the signature check fails, we raise a ValidationError which
counts as an HTTP 200 for some providers (it's not the case if they
expect a specific string). (Adyen, Paypal, Sips, Stripe)
3. If a ValidationError is raised when processing the feedback data, it
is allowed to bubble up to the provider. (Alipay, Ogone)
The issues are respectively addressed as follows:
1. If the acquirer implements payments with redirection, make sure that
if either makes a request to the provider to validate the data or
that it verifies the signature. Verifying the origin of the request
is not enough: the payload must be checked too.
2. Instead of raising ValidationError's, raise an HTTP 403 FORBIDDEN
error if the signature check fails.
3. Wrap the call to `_handle_feedback_data` of the webhook method inside
a try/except clause to catch any ValidationError, log a warning, and
acknowledge the notification to avoid having the provider disable the
webhook because of too many failures.
