Investigate logging configuration and logging tests #620

@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

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.
