pg_upgrade: Parallelize retrieving relation information.

This commit makes use of the new task framework in pg_upgrade to
parallelize retrieving relation and logical slot information.  This
step will now process multiple databases concurrently when
pg_upgrade's --jobs option is provided a value greater than 1.
