> We only have minimal test coverage of {{IF \[NOT\] EXISTS}} conditions for
> DDL statements. I think dtests are the right place to add those tests.
> We need to cover:
> * {{CREATE KEYSPACE IF NOT EXISTS}}
> * {{DROP KEYSPACE IF EXISTS}}
> * {{CREATE TABLE IF NOT EXISTS}}
> * {{DROP TABLE IF EXISTS}}
> * {{CREATE INDEX IF NOT EXISTS}}
> * {{DROP INDEX IF EXISTS}}
> * {{CREATE TYPE IF NOT EXISTS}}
> * {{DROP TYPE IF EXISTS}}
> The tests should also ensure that InvalidRequestExceptions are thrown if, for
> example, you try to drop an index from a keyspace that doesn't exist
> (regardless of whether {{IF EXISTS}} is used).
