PASS

Once merged, I can run all tests in Jenkins and any failures should be fixable through updated hostames.

Alternatively, I can run all tests in Replicated locally. Will update here depending on which way I go.

Edit: Running all tests sequentially, locally:

stackablectl release install dev
make run-dev
scripts/run-tests --parallel 1 --skip-release

This PR doesn't change the behaviour. This is why there are no tests for external listeners.
