refactor(workflow): Update default memory consumption values and enhance experiment manifests

- Set default values for MemoryConsumptionPercentage and MemoryConsumptionMebibytes to "0" in the NodeMemoryHog configuration, ensuring clarity in resource allocation.
- Removed unnecessary NODE_LABEL entries from the node-memory-hog and node-cpu-hog manifests to streamline configuration.
- Added comprehensive permissions for various Kubernetes resources in the experiment manifests, enhancing operational capabilities.
- Improved overall manifest structure by ensuring consistent labeling and resource definitions across chaos experiments.
