Upgrading Clusterloader2 Prometheus-operator Pkgs

[Miseratio]

What would you like to be added:
Upgrade the Prometheus-related packages and manifests used by ClusterLoader2 to newer versions.

Why is this needed:
I am a developer currently working on benchmarking a custom Kubernetes cluster and have noticed that the Prometheus packages and images relied upon by ClusterLoader2 are outdated and lack modularization. To be specific, the Prometheus manifests were last updated to version 0.46.0 three years ago.

The Prometheus Operator repository now provides kube-prometheus, a dedicated package tailored for Kubernetes environments. However, the newer Prometheus images are incompatible with the existing outdated manifests in ClusterLoader2, making updates challenging. A specific example of upgrade benefit is the node-exporter DaemonSet listed in the TODO comments of the prometheus.go, which is already implemented in the kube-prometheus package but remains incomplete in ClusterLoader2.

Additionally, updating to newer image versions would help address CVEs in older versions, ensuring a more secure and reliable benchmarking environment. This upgrade would modernize ClusterLoader2, resolve compatibility issues with new images, and enhance the maintainability of benchmarking workflows.
