Add a dask-sql parser and component

Thanks to @romain for his nice comment to this medium post on dask-sql, where he asks if it would be a good idea to add dask-sql as a parser and a connector to Hue. I would be very happy to collaborate on this! Thank you very much for proposing this.

Looking at the code (and your very nice documentation), I have the feeling that adding a new "dask-sql" component should be rather straightforward - whereas adding the SQL parser would probably be a bit more work.
I would probably start with the presto dialect and first remove everything that dask-sql does not implement (so far).

Creating a correct parser seems like a really large task to me and I would be happy if you have good suggestions on how to properly sync Hue with the SQL dask-sql understands and if you have any suggestions on how to speed up the development.

I would also be happy for any guidance on how to reasonably split this large task and if you think in general if this is a good idea.

Thanks!
