Group id is mandatory configurtion option for confluent_kafka 2.4.0+

The group.id parameter has been optional before 2.4.0 version of
confluent_kafka relased on 7th of May. This started to fail our
integration tests (cool).

This PR adds "group.id" as extra field and sets the defaults for
integration testing.
