      We have made a lot of changes to the balancer. As a result, clusters with a high number of sharded collections may see slower balancing. In trying to find how many clusters have a high number of sharded collections, we realize that serverStatus doesn't give us this information.

      We should track the number of sharded collections in a cluster and place that information in serverStatus. It would help to backport this to all the versions.

      something like "numShardedCollections" or "catalogStatus.shardedCollections" may suffice.

      This can be a lazy/slow count, aka can we do this in a way that doesn't impact customer workloads?
