Add Istio Annotations to Metrics Server

For the specified package, add an annotation to all pods with the version of Istio. This ensures that pod sidecars are refreshed when Istio updates. The Istio version annotation should not contain the -bb.x suffix, so that pods are only rolled when upstream Istio updates.

AC (when package has helm values to specify annotations):

• In the BB chart/templates/<package>/values.yaml file add values so that the istio annotation is added to all pods in the package. See this example for more details.
