> Right now, we always hit the primary replica for meta and fallback to the secondary replicas
in case of a timeout. This can hamper performance in scenarios where meta becomes a hot region
e.g. cluster ramp up..clients dropping connections etc.
> It's good to have a load distribution approach on meta's secondary replicas with fallback
to primary if we read stale data.
