DRILL-7048: Implement JDBC Statement.setMaxRows() with System Option
This introduces support for JDBC's Statement.setMaxRows(int) API, which can help Drill execute a query much faster if it knows that not ALL the records in the resultset will be consumed upfront.
This Commit introduces the core changes to support the feature within Drill's execution engine
