Review Comment:
> Thus my suggestion is should we let's limit the scope to "all tables
belong to the same tenant, not necessarily 'default'" first?
This PR takes care of this scenario specifically. At present, queries work
fine when we hit brokers directly of a non-default tenant as @ankitsultana
mentioned. We want to allow those queries to be pushed down to broker from
controller as well.
