vertical-pod-autoscaler-app release v3.0.0

Added

• Add cilium network policy so that the crd-install job can reach the k8s api to install the CRDs.
• README: doc improvements

Changed

• Remove push-to-app-collection jobs for onprem providers since this app became a part of default apps bundle.
• Moved to chart dependency
• ⚠ Major upgrade, breaking changes
  • values structure changes. We rely on a subchart, meaning all of previous setup goes to a vertical-pod-autoscaler section
  • the upstream repo has changed and thus as did the helm chart config
