Abort the balancer if an upgrade is in progress

      Description

      Running the balancer during an ongoing upgrade has a negative affect, since DNs do not actually delete blocks. This means the balancer is making lots of extra replicas and not actually reducing the disk utilization of over-utilized nodes.
