Add Kubernetes CPU/Mem usage totals
Right now we are providing average CPU/Memory usage for k8s pods, which is helpful for understanding how an individual pod is performing. This can be particularly useful for understanding canary vs. stable tracks.
What is equally important though is the overall trend across all nodes, which would be the total CPU and Memory consumed. This MR adds two additional charts to do just this.
This also removes the regex for filtering out canary pods. Since CE doesn't have Canary support, they should be included single series.
