[CLAMP] Update clamp to allow re-play of the test

Today a docker restart is failing
because we try to enrich a certified artifacts
Like for other basic_* tests, if the service is already distributed
we may just consider creating the loop (bypass the model onboarding part)
so we can run the test as a replay and use it for parallel tests
