Log when daemons trigger a reload in response to config changes

Summary:
Ref T10811. This puts an explicit message in the log when a module triggers a reload.

• Also, lift declare(ticks = 1) up to top level.
• Make sure verbose messages hit the disk log, not just the database log.

Test Plan: Ran daemons, changed config, saw them reload automatically with an explicit message.
