Allow out of quota failure status code to be 413 or 403

The commit I2bb8a60ef254afbfed514cfeebe75355d0de4475 tries to change
error codes of quota-out to suitable ones (HTTPForbidden).
We need to allow both HTTP413 and HTTP403 because branchless Tempest
needs to support both master and icehouse/stable branches.
