> As a user, I would like to be able to specify a LIMIT clause on my SQL queries.
> Work involved:
>  * Add Limit to LogicalPlan enum
>  * Write query planner code to translate SQL AST to Limit (SQL parser that we use already supports LIMIT)
>  * Implement LimitRelation (look at filter.rs as a guide since it is quite similar)
