REPACK: do not require REPLICATION or LOGIN 
Although REPACK (CONCURRENTLY) uses replication slots, there is no
concern that the slot will leak data of other users, because the
MAINTAIN privilege on the table is required anyway; requiring
REPLICATION is user-unfriendly without providing any actual protection.

A related aspect is that the REPLICATION attribute is not needed to
prevent REPACK from stealing slots from logical replication, since
commit e76d8c749c made REPACK use a separate pool of replication
slots.

Similarly, there's no reason to require that the table owner has the
LOGIN privilege.  Bypass the default behavior in the background worker
launch sequence.

Because there are now successful concurrent repack runs in the
regression tests, we're forced to run test_plan_advice under
wal_level=replica, so add that.  Also, move the cluster.sql test to a
different parallel group in parallel_schedule: apparently the use of the
repack worker causes it to exceed the maximum limit of processes in some
runs (the actual limit reached is the number of XIDs in a snapshot's xip
array).
