#B-14918 [solr] Logging and/or metrics around searcher warming times

Since overlapping searcher is a know issue causing cluster instability, we should start logging how long cache warming is taking. Ideally there's a logging config that can enable this, less ideally a script that loads polls for stats and loads into graphite.

Actually... I just found this in New Relic. But it's only Averaged (over time) and Agrregated (Over all the hosts), I'm not terribly certain it will help pin point bad behavior, but is good for an overall view. Transaction traces do show some outliers.
