Have pg_rewind run crash recovery before rewinding
If we don't do this, the rewind fails if the server wasn't cleanly shut
down, which seems unhelpful serving no purpose.
Also provide a new option --no-ensure-shutdown to suppress this
behavior, for alleged advanced usage that prefers to avoid the crash
recovery.
