Investigate logging configuration and logging tests

[maltesander]

@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

hdfs-operator/tests/templates/kuttl/logging/04-install-hdfs-automatic-log.yaml.j2

Line 31 in 526f589

hdfs:

.

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

• hdfs-operator/rust/crd/src/lib.rs

  Line 1036 in 526f589

  pub enum NameNodeContainer {

• hdfs-operator/rust/crd/src/lib.rs

  Line 1174 in 526f589

  pub enum DataNodeContainer {

• hdfs-operator/rust/crd/src/lib.rs

  Line 1296 in 526f589

  pub enum JournalNodeContainer {

• hdfs-operator/rust/operator-binary/src/product_logging.rs

  Line 156 in 526f589

  "hdfs",

Not sure how that can work, this needs investigation.

Don't know if it's acceptable to rename the containers back to hdfs but this would make them inline with all other operators that name the main containers consistently with the product name, for example airflow, druid, ...
