Title: Update docs for configuration changes in 3.0

I've tried to make a good start on updating the docs for the configuration changes recently merged into the 3.0 branch.

I tried to consolidate some of the duplicated documentation around configuration and add namespacing where I could. I've also been removing the `versionadded` and `versionchanged` tags from 2.x as they aren't really relevant in the 3.x docs.
