```security_rolling_upgrade_test``` may change the security listener and then restart Kafka servers. ```has_sasl``` and ```has_ssl``` get out-of-date due to cached ```_security_config```. This PR offers a simple fix that we always check the changes of port mapping and then update the sasl/ssl flag. issue: https://issues.apache.org/jira/browse/KAFKA-10257 ### Committer Checklist (excluded from commit message) - [ ] Verify design and implementation - [ ] Verify test coverage and CI build status - [ ] Verify documentation (including upgrade notes) ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
