--------------------------------------------------------------------
{{AssignmentsPlacementDriver.getAssignments }}javadoc says the method returns a
future, which may completes with {{{}`null{}}}` if no assignment found for
given replication group id.
I guess, the method should never ignore missed assignment, and should either
return a `null` if any assignment was missed or failed with error.
What is expected behavior for this new method?

> At the moment, it is not possible to get assignments for several replication
> groups at once.
> {{AssignmentsPlacementDriver}} has the following method only to get
> assignments.
> {code:java}
> CompletableFuture<TokenizedAssignments> getAssignments(ReplicationGroupId
> replicationGroupId, HybridTimestamp clusterTimeToAwait);
> {code}
> But sometimes you need to get assignments for a list of several replication
> groups, so it would be nice to have a separate method for this, something
> like the following:
> {code:java}
> CompletableFuture<List<TokenizedAssignments>>
> getAssignments(List<ReplicationGroupId> replicationGroupId, HybridTimestamp
> clusterTimeToAwait);
> {code}
