Grafana Pods dashboard updated memory metrics

We’ve updated the Pods dashboard so it displays both the actual container memory usage (container_memory_working_set_bytes) next to the previous metric including caches (container_memory_usage_bytes). You can find this dashboard in your grafana deployment as Pods v2.

For now this is deployed as a separate dashboard next to the existing one. The end-goal is to merge this together with the upstream dashboards we use, once we have moved our monitoring setup from the coreos/kube-prometheus chart to the new stable/prometheus-operator. More on that in a later update 😃.
