> It should be possible to set a trigger on any metrics exposed by the Metrics API using
a threshold value. Supporting {{waitFor}} may not be possible or useful for all metrics. For
those we will implement proper trigger support (such as searchRate) However, a naive implementation
might be to just poll the value of the metric frequently and if it is consistently above the
threshold, fire the trigger.
