> {{tablesByIdVV.update()}} inside {{TableManager#updateAssignments}} initiates
> async RAFT groups' start, but its future supplier returns
> {{{}completedFuture(null){}}}, so there is no causal dependency between
> completion of what {{update()}} returned and the futures that start RAFT
> groups; hence, there is no causal dependency between completing 'table
> created' future and RAFT groups start.
> While {{updateAssignmentsInternal}} is fully synchronous, this is not a
> problem. But in IGNITE-18170 we make it async, and here the race starts
> manifesting itself.
> Probably, update supplier should return a future depending on RAFT group
> start future and not just a completed future.
