walreceiver uses a temporary replication slot by default

If no permanent replication slot is configured using
primary_slot_name, the walreceiver now creates and uses a temporary
replication slot.  A new setting wal_receiver_create_temp_slot can be
used to disable this behavior, for example, if the remote instance is
out of replication slots.
