Title: Pauseless rejoin fixes

This includes various fixes for pauseless rejoin.

- Fixed a race condition on clearing the rejoin overflow dir. The rejoin coordinator will clear the overflow dir, each site only cleans its own file at the end of rejoin.

- Add a workaround to get the rejoin snapshot txnId if the snapshot was queued and succeeds later. Rejoining site will request to be notified if the rejoin snapshot is queued and then succeeds later, so that it can get the snapshot txnId eventually.

- Various log message improvements.
