Ed Hennis 5f087f6446 Improve node store rotation ...

- Add a special case to healthWait() to not pause when the server is
  DISCONNECTED.
- Log sequence differences at the start and end of rotation.
- Limit copy-forward to ledgers we're not about to delete, and unknown.
  (Changes rotationInFlight_ from a bool to a LedgerIndex.)
- Set the "rotation in flight" index right at the beginning of the rotation
    - Because the node copy process can take a long time, other ledgers may
      get validated. Any reads for those ledgers have the potential to be
      served by the archive DB and thus lost, too. Why wait?
- Add an assertion suggested on @vlntb in #7763.
- Don't wait as long for ledgers that should be built soon.
- Rescue nodes from the tree node cache, too.
