[dev-v2.8] rancher-logging rke2 patch kubelet logs volume mount to follow rotates

[alexandreLamarre]

Issue:

SURE-7276

Problem

fluentbit cannot follow log rotates for the hostpath /var/lib/rancher/rke2/agent/logs/kubelet.log on rke2

Solution

Mount the hostpath directory /var/lib/rancher/rke2/agent/logs to prevent the volume bind from locking the file kubelet.log so that fluentbit can follow file changes

Validation steps

• Ensure all container images have repository and tag on the same level to ensure that all container images are included in rancher-images.txt which are used by airgap customers.

  Ex:- 
    longhorn-controller:
      repository: rancher/hardened-sriov-cni
      tag: v2.6.3-build20230913
