Expose more granular metrics around balancing round

    • Sharding EMEA
    • Fully Compatible

      We observed that in large cluster with lots of collections/chunks the balancer can take several seconds to decide which chunks to move in each round.

      The goal of this ticket is to include this time in the round details stored in config.actionlog

      E.g.

      {
        "times":
          "selectionTimeMillis": <>,
          "throttleTimeMillis": <>,
          "migrationTimeMillis": <>,
      }
