      Move the balancer to be on the CSRS primary and remove it from mongos. This task includes making the following changes:

      • Ensuring that only the CSRS primary runs the balancer and that step down interrupts any active migrations (or there is a way for the new primary to resume monitoring any active migrations).
      • Acquisition of the balancer dist lock
      • Implement the balancer state machine
