Description

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)
