pg_upgrade: Parallelize subscription check. This commit makes use of the new task framework in pg_upgrade to parallelize the part of check_old_cluster_subscription_state() that verifies each of the subscribed tables is in the 'i' (initialize) or 'r' (ready) state. This check will now process multiple databases concurrently when pg_upgrade's --jobs option is provided a value greater than 1.
