Resharding, whether dynamic or manual, has not previously clean up the old bucket info objects or shard objects. That has led to an accumulation of unneeded objects that likely impacts performance. BZ#1627562 addresses one aspect of this issue, and automatically cleans up these objects after both successful and failed reshardings. But for existing clusters that have experienced this accumulation of unneeded objects, we need an administrative tool to clean these up. See also: https://bugzilla.redhat.com/show_bug.cgi?id=1627562
