Check LTSS product to verify

[jesusbv]

Description

After a non free extension has been activated successfully on a PAYG system, RMT calls ZypperAuth verify_instance method without any other information, the SCC verification of the activation would fail as there is no product info to check against

Adding the product id present in the request params, that way RMT can fetch the product class and verify properly
