Previously if LDS/RDS were missing or improperly configured RPCs would fail with "UNAVAILABLE: NameResolver returned no usable address errors". That is very confusing and not helpful for debugging. Ideally we'd also include the node id in this error message, but that's a bit more involved and this is a huge improvement even without it. b/237539851
