> set "SqlToRelConverter.ConfigBuilder#expand" default to false

> Key: CALCITE-3870

> Project: Calcite
> Issue Type: Bug

> Now the default "expand" in SqlToRelConverter.ConfigBuilder is true but in
> calcite's main process, actually, it is false(
> `withExpand(THREAD_EXPAND.get())`)
>
> That leads we need to explicitly set `withExpand` to false when we use
> SqlToRelConverter.
>
> So I think we should change the default to "false" in
> SqlToRelConverter.ConfigBuilder.
