modules_k/rls: RLS full-state NOTIFY requests now sent by notifier process(es)

- Also modified the notifier process stuff to only work when in
  DB only mode.  This is because the full-state handling stuff
  in the notifier processes relies on DB only mode.
- Leaving the full-state stuff outside of the notifier process
  didn't work because there was a row update race between the
  notifier process and non-notifier process when full-state and non-
  full-state NOTIFY requests were generated at the same time.
- This ensures that (with default options) you get at most one NOTIFY
  (or set of NOTIFYs when splitting large NOTIFYs is enabled) per
  5s per watcher from RLS.
- It also helps spread out the NOTIFY generation load more evenly
  across time.
