Move "wild" config types to new code


Move "wild" config types to new code

Ref T12845. This is the last of the hard-coded types.

These are mostly used for values which users don't directly edit, so it's largely OK that they aren't carefully validated. In some cases, it would be good to introduce a separate validator eventually.

Test Plan: Edited, deleted and mangled these values via the web UI and CLI.
