Enable ability for user to pass in a list of CBO rules that should be…

Given the intent here is to allow users to turn off specific CBO rules which may be problematic, we'll need a place where they can see how to configure them, and what constants/enums they need to supply.

I think this is as good a time as any to start the beginnings of a docs page about Dask-SQL's use of Calcite's CBO.

LGTM, thanks for the work @jdye64! Could we maybe open an issue to track the follow up work that needs to happen here?
