Description
Add MOVE_TO matching profile segments to the list of matching in-flight loads so we account for moving segments in making replication decisions.
I am observing a cluster using partial loads and even after #19843 I am seeing what appears to be excessive replication churn. This seems to be a contributor
Release note
minor bugfix to how Druid accounts for partial segments who are actively being moved between historicals that will reduce unnecessary segment load churn.
