@fedinskiy can you confirm you run smoke check on SASL_SSL and Kafka SSL scenarios in TS?

[fedinskiy]

I have run both Openshift and baremetal tests in framework in all three examples/kafka* nodules. I am running TS tests now

[fedinskiy]

Kafka SSL test in TS (messaging-kafka-ssl module) went just fine.

There is a failure in KafkaGratefulShutdownIT (will investigate it next week) and in Snappy tests (they read kafka logs manually, so we need to change the directory)

Failure of the OpenShiftS2iQuickstartUsingDefaultsIT in OCP native mode is not related. Let's improve in follow-up PR's if there are fixes required for TS.

This also needs to be backported to the other supported branches too, since this also enables the now supported usage of Kafka in KRaft mode without deprecated Debezium.
