add zend-6.1 to rest_api cartridge_type_test
Temporarily disable code that breaks test

Temporarily disable the test code that tries to deploy an artifact_url
because we don't have the artifacts created and servable from anywhere.
Re-enable once we figure out how to precreate the artifacts and make
them available.
