* Enable configuring kubernetes annotation metrics

With kubernetes/kube-state-metrics#1468 kube-state-metrics v2.2.0 added the possibility to configure annotation metrics, similar to how label metrics are currently configured.
This change adds a configuration option for configuring annotation metrics to this helm chart.
