Run all minor setup checks on all configured database hosts

Browse source 
Summary:
Fixes T10759. Fixes T11817. This runs all the general sanity/configuration checks on all the active servers.

None of these warnings are very important, and this doesn't change any logical stuff.

Depends on D16904.

Test Plan: Painstakingly triggered each warning, verified that they rendered correctly and that messages told me which host was affected.
