We're setting these on the query frontend server. Does GRPC negotiate the settings between the 2? Did we see something that makes us think we should set this?

I was reading in this area recently and also noticed the #1596 and thought to put up the PR. I think client and server settings are separate, and so without this, we are using the default values on the client. We could certainly do more testing to confirm, like clamping down the max bytes on the client and seeing if the server responds in a way that represents the negotiation.

If we want to do this change, we should repro the issue and then confirm this fixes it.

I mixed on this. Here we're only using the configuration that we already expose, so to test we'd be testing the deeper levels of gRPC. I haven't heard back on #1596.
