The range is implied and documented by having a config for PHOENIX_META
priority and config for PHOENIX_INDEX priority.

> If the RS hosting the system table gets swamped, then we'd be bottlenecked
> waiting for the response back before running a query when we check if the
> metadata is in sync. We should run endpoint coprocessor calls for
> MetaDataService at a high priority to avoid that.
