    Nice, but I might move this to a method:
    
    ```
    FixtureBuilder builder = ClusterFixture.builder()
        .withTempDir(dirTestWatcher)
        .configProperty(...) ...
    ```
    
    Reason: if this has to go into the constructor, then every constructor use 
must change, and tests must create a temp directory even when not needed. But, 
if passed in using a builder method, then we can use it regardless of how we 
create the builder object, and the directory is optional.
