             Summary: Consider providing standard set of users in system tests
                 Key: KAFKA-10443
                 URL: https://issues.apache.org/jira/browse/KAFKA-10443
             Project: Kafka
          Issue Type: Test
          Components: system tests
            Reporter: Ron Dagostino


As part of the KIP-554 implementation we decided to exercise the AdminClient interface for creating SCRAM credentials within the system tests.  So instead of bootstrapping both the broker and the user credentials via ZooKeeper (`kafka-configs.sh --alter --zookeeper`) before the broker starts, we bootstrapped just the broker credential via ZooKeeper and then we started the brokers and created the user credential afterwards via the AdminClient (`kafka-configs.sh --alter --bootstrap-server`).  We did this by configuring the admin client to log in as the broker.  This works fine, but it feels like we should have a separate "admin" user available to do this rather than having to authenticate the admin client as the broker.  Furthermore, this feels like it might be a good pattern to consider everywhere -- whenever we create a broker user we should also create an admin user for tests that want/need to leverage it.
