Description

IMPALA-5354 added support for INSERT hints into Kudu tables, but the hints don't work for CTAS.

It looks like the CreateTableAsSelectStmt constructor doesn't pass any hints to InsertStmt.createInsert(). The parser will also need to be modified.

While this came up in the context of Kudu tables, the INSERT hints for non-Kudu tables should work as well.
