SQL BULK INSERT (fb-1749) (#2291)

 SQL BULK INSERT

This change is to support a BULK INSERT/REPLACE statement that adds the ability to 1) take its input from a file, url or in-line blob 2) to map from the input source to the target columns
3) to transform data (using sql expressions) before inserting
4) support csv and ndjson formats

* improving test coverage

* increase test coverage again

* refactoring for handling transformation with types other than id and int

(cherry picked from commit 8f660a5)
