Summary:
When configuration is set incorrectly (e.g., of the wrong type), detect and repair it by setting it to the default value. A setup warning will be raised separately.
Notably, this removes the need to hard-code all the class types.
This runs separately from the "invalid config" check because we need to run it on every page, but do setup checks only once per restart (some of them are slow).
Also dirty setup when we edit configuration.
Test Plan: Set config incorrectly on purpose, saw Phabricator correct it on restart and on every subsequent page load until it was fixed.

Summary:
This is basicaly a light version of D4286. The major problem with D4286 is that it's a huge leap and completely replaces the setup process in one step.
Instead, I want to do this:
- Add the post-setup warnings (yellow bar with "6 unresolved warnings...").
- Copy all setup checks into post-setup warnings (so every check has an old-style check and a new-style check).
- Run that for a little bit and make sure it's stable.
- Implement fatal post-setup checks (the red screen, vs the yellow bar).
- Run that for a little bit.
- Nuke setup mode and delete all the old checks.
This should give us a bunch of very gradual steps toward the brave new world of simpler setup.
Test Plan:
- Faked APC setup failures, saw warnings raise.
- Verified that this runs after restart (get + set).
- Verified that this costs us only one cache hit after first-run (get only).
