Enable Kafka consumer offset committing
It appears that reactor-kafka is setting auto.commit property to false,
which makes our CSITs fail nondeterministically due to automatic reset of
consumer offset.
By acknowledging manually, we will mark every message for committing,
which will be performed according to ConsumerConfiguration.
This way, Kafka broker should persist consumer offset.
