Investigate logging configuration and logging tests

@Jimvin discovered problems with configuring logging.

Configuring logging on role level did not work, role group level worked with the following config:

  journalNodes:
    roleGroups:
      default:
        replicas: 3
        config:
          logging:
            enableVectorAgent: true
            containers:
              journalnode:
                loggers:
                  ROOT:
                    level: DEBUG
                console:
                  level: DEBUG
    configOverrides: *configOverrides

In the logging tests we use the hdfs container https://github.com/stackabletech/hdfs-operator/blob/526f58925ca0ea0f543819f05516d3b70e1e28f3/tests/templates/kuttl/logging/04-install-hdfs-automatic-log.yaml.j2#L31.

Looking at the code, it seems to be hdfs as well:

• https://github.com/stackabletech/hdfs-operator/blob/526f58925ca0ea0f543819f05516d3b70e1e28f3/rust/crd/src/lib.rs#L1036
• https://github.com/stackabletech/hdfs-operator/blob/526f58925ca0ea0f543819f05516d3b70e1e28f3/rust/crd/src/lib.rs#L1174
• https://github.com/stackabletech/hdfs-operator/blob/526f58925ca0ea0f543819f05516d3b70e1e28f3/rust/crd/src/lib.rs#L1296
• https://github.com/stackabletech/hdfs-operator/blob/526f58925ca0ea0f543819f05516d3b70e1e28f3/rust/operator-binary/src/product_logging.rs#L156

Not sure how that can work, this needs investigation.

Beginne mit dem Logging-Test-Template unter tests/templates/kuttl/logging/04-install-hdfs-automatic-log.yaml.j2 und den referenzierten Rust-Definitionen in rust/crd/src/lib.rs und rust/operator-binary/src/product_logging.rs. Vergleiche die Logging-Konfiguration auf Rollenebene und auf Rollengruppenebene und führe anschließend die Logging-Tests aus, um festzustellen, warum die hdfs-Containerkonfiguration scheinbar funktioniert und was geändert werden muss.
