Personally I don't see need for apply_worker_timeout, no idea why that
can't use wal_receiver_timeout, the mechanics are exactly same, and it's
IMHO only needed because default tcp keepalive settings are usually too
generous. As for apply_worker_launch_interval, I think we want different
name so that it can be used for tablesync rate limiting as well.
