chore(docs): organize configurations.rst

[erikayasuda]

Organizing our configuration docs. We should eventually switch over to using Envier for all of these so they can be auto-generated and the raw .rst file is much more clean, but for now this will help with readability. No content was changed, just reshuffling of the ordering and some grouping.

See the sample generated doc here compared to what is published as latest.
