James E. Blair 07c83f555d Add ZK cache stats
To observe the performance of the ZK connection and the new tree
caches, add some statsd metrics for each of these.  This will
let us monitor queue size over time.

Also, update the assertReportedStat method to output all received
stats if the expected stat was not found (like Zuul).
