[ENH] Making Fugue[dask] depend on Dask-sql

[goodwanghan]

Is your feature request related to a problem? Please describe.
Currently dask-sql has integration with Fugue. The problem is some Fugue change will break this integration. Also Fugue-dask by default relies on the qpd project to support SQL, which I want to totally deprecate.

Describe the solution you'd like
Remove the dependency of fugue from this repo
Add the dependency of dask-sql on Fugue side
fugue-project/fugue#454

It's a good time to make the change now because you no longer depend on conda and Calcite.

Can you please wait a little bit for the related code change (I will make a PR to remove Fugue) before your next release?

We were planning on cutting a release EOD today/early tomm, to bump our dask version dependency to be compatible with the upcoming Rapids release.
That being said we're happy to do another patch release in the coming week or two and we can add the relevant code changes in then.
