Add "Developer" and "Access Log" config option groups, some types

Summary:
- Add a "developer" option group.
- Add an "access log" option group.
- Render the types "bool", "int" and "string" in a more tailored way.
- Add a config check for dead config. Right now this serves as a "TODO" list of things that need to be migrated.

Test Plan: Looked at config options, setup issues. Edited bool, int, string options.
