[mbelur]

##Issue:
rancher/rancher#43856

##Problem:
Create new rancher-csp-adapter chart for 2.9 rancher

##Testing:

scenario 1 (fresh install):

On an EKS cluster (k8s version 1.27), install locally built rancher with cspAdapterMinVersion: 104.0.0+up4.0.0-rc1
Validated the support config and licence entitlement functionality. Created a downstream EKS cluster with 21 nodes (with 1 entitlement) to trigger out-of-compliance message. Scaled down the cluster to 17 nodes, validated that the out-of-compliance message is no longer displayed. Scaled back up to 21 nodes, validated the out-of-compliance message popped up.

scenario 2 (upgrade scenario):

Start with an EKS cluster (k8s version 1.27), install rancher 2.8.3 with csp-adapter 3.0.1
Upgrade rancher to locally built rancher with cspAdapterMinVersion: 104.0.0+up4.0.0-rc1
Update charts url repo/branch and upgrade csp-adapter version to 104.0.0+up4.0.0-rc1
Validated the support config and licence entitlement functionality. Created a downstream EKS cluster with 21 nodes (with 1 entitlement) to trigger out-of-compliance message. Scaled down the cluster to 17 nodes, validated that the out-of-compliance message is no longer displayed. Scaled back up to 21 nodes, validated the out-of-compliance message popped up.

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
  

• Add a 👍 (thumbs up) reaction to this comment once done. CI won't pass without this reaction to the github-action bot's latest validation comment.
• Approve the PR to run the CI check.
