[Bug] Hostname information missing from kubelet logs

[Jono-SUSE-Rancher]

Default rancher-logging configuration collects the kubelet and journald logs however the logs lack corresponding node or hostname references. We are going to be adding in those references.

Retest Pass : Node info for rke2 rancher-logging chart are coming in logs for local as well as downstream cluster.

Details

• Rancher v2.15.0-alpha8
• RKE2 custom cluster (single all-role node)
• rancher-logging 109.0.0+up4.10.0-rancher.24

Validation Steps:

• Provisioned an RKE2 custom cluster and installed rancher-logging 4.10.0-rancher.24 (dev branch) using default chart values.
• Verified that additionalLoggingSources.rke2.enabled was automatically enabled.
• Created the ClusterFlow and ClusterOutput resources provided in the QA instructions to capture logs from the rke2 journald aggregator.
• Accessed the rancher-logging-root-fluentd-0 pod and inspected the logs written under /tmp/logs.
• Verified that log records contain node information matching the cluster node name.

DownStream Cluster
