Add option -N/--no-sync to pg_upgrade
This is an option consistent with what the other tools of src/bin/
(pg_checksums, pg_dump, pg_rewind and pg_basebackup) provide which is
useful for leveraging the I/O effort when testing things. This is not
to be used in a production environment.
All the regression tests of pg_upgrade are updated to use this new
option. This happens to cut at most a couple of seconds in environments
constrained on I/O, by avoiding a flush of data folder for the new
cluster upgraded.
