add 2nd level TMA metrics to chart

[harp-intel]

example:

This is a very cool feature and makes the TMA page more actionable. Would it require a 3rd level - for example for memory - its not useful knowing memory boundedness without knowing if its actually latency or bw?

Challenge is that latency and bandwidth are something like 5th level metrics. The %'s start to fall apart at that depth so that chart may become incomprehensible. I think we need a better/dynamic UI widget that expands. For now, see the 'All Metrics' tab.
