Review comment:
Well, the reason the ZooTabletStateStore only accepted one was because
it can only ever have one... because the root table that uses the
ZooTabletStateStore can never have more than one tablet, and therefore, there
can never be more than one assignment being updated. That's not true for the
other stores, because the metadata table can split into multiple tablets, and
so can user tables.
