> We'll need to add the StatisticsCollector to existing tables so that stats are kept for
these tables. We typically do that on first connection to the cluster in ensureTableCreated
when our system table is created by walking through the existing Phoenix tables. We only need
to do it if the system table already exists (otherwise, it's a new installation).
