My main question is on the paging setup.  I don't mind if this is added later, 
but the `QueryResult` that is used for paging doesn't have changes to add 
warning.

Overall I am +1 to this.  Please add the builder warning support, and will 
leave up to you on pager in scope or not for this JIRA.

> There isn't a way to get query warnings generated via \{{ClientWarn}} using 
> the existing \{{ICoordinator}} interface. The simplest possible change here 
> would be to...
> 1.) Make sure we activate warning collection before queries start.
> 2.) Rip warnings out of \{{ClientWarn}} when queries return.
> 3.) Include those warnings when we create \{{SimpleQueryResult}}.
> {\{QueryResult}} might not need to expose the warnings, given not all its 
> implementations would be expected to have them, but we could just return an 
> empty list of warnings by default.
