As of SERVER-85441, the balancer is being used to test the behavior of the system when moveCollection is called in the background. We would like to keep this coverage for the 8.0 world where collections are not tracked upon creation, but the balancer is currently only issuing moveCollection commands if there are unsharded collections tracked on the sharding catalog.

We would like to change this behavior if we are running under featureFlagTrackUnshardedCollectionsUponMoveCollection so that the balancer will issue moveCollection commands for untracked, unsharded collections.

The behavior should remain the same (issue moveCollection for tracked collections) if featureFlagTrackUnshardedCollectionsUponCreation is enabled.
