We have a lot of canary timeouts. It would be nice if we made them easier to understand, for sheriffs. Eventually we'll have stuff in monarch, but in the meantime...

In ReportStage we already summarize historical per-stage times. Perhaps we can call out louder the specific stages that took unusually long?

Or, have the stage itself realize that it took unusually long (via cidb query) and color itself yellow in the waterfall.
