Fix CPU/Memory usage metrics when using prometheus operator. (#632)

Browse Source 
Cluster CPU and Memory usage cannot be sum by node as it is rendered as single cluster metrics. Without this changes, the cluster graphs (standard and pie) shows data only from first (or latest) nodes.

For pod specific metrics, when we use prometheus operator the `container_` metics are doubled. Restric search to get those have image tag.
