See if we can just reuse the test we have for the rewrites without copying them.

Hmm, I thought the whole idea of the config is so people can just drop in a rewriter and use it? So I'm not sure if we need this.

So we would like users to be able to add a rewriter and pass in the name to be able to use it. It's not just about enabling a rewriter.

Added a RewriteDriver and supporting classes (config, result, module).
This driver is the link between Presto-Parser and Presto-Coresql's rewriters, allowing us to apply 0 or more of Presto-Coresql's rewrites to a SQL statement passed to Presto-Parser.
