Improve canary detection
Right now with our metrics feature, we can detect a canary release and display those results alongside the current GA version.
Unfortunately to support alerts for pre-packaged metrics, and to move to a database driven model, we had to move the canaries into their own chart.
We should:
- Fix this situation and add support for canary memory/cpu to be shown on the same chart as the GA version
- At the same time, look to improve how we manage and detect canary metrics
