Upgrade Notices

The 2.0 release of the k8smonitoring Helm chart includes major changes from the 1.x version. Many of the features have been rearranged to be organized around features, rather than data types (e.g. metrics, logs, etc.). This will require looking at Migration guide from k8smonitoring and possibly using their migration tool available at https://grafana.github.io/k8smonitoringhelmmigrator/ if you have any custom configuration or flags set in the values.yaml.
