docs: // cronStatsHandler gathers metrics about the state of LogDog and sends it to tsmon.
  // This collects all namespaces, and fires off one task per namespace x metric combination.
  //
  // This gathers the following stats:
  // * Number of unarchived streams between 70-72hr old (after creation).
  // * Number of unarchived streams between 22-24hr old (after creation).
