Fix handling of replication slots on the master.
...
Master shouldn't keep a replication slot for the members that
replicate from other members instead of the master (replicatefrom).
Otherwise, the master will keep collecting WAL segments that won't
be requested ever. Of course, if the destination of replicatefrom
is not part of the cluster, master should create the slot.

When running patroni with a superuser different than the os-user, the connection

Support new replicas without the master.
...
The replication method should have no_master flag set and
support getting the base backup from some external storage
(i.e. S3). At the moment we only support initialization of
replicas in the already existing cluster when no master is
present, since there is no 'one fits all' way to decide whether
to run initidb or wait for the replica data storage to become
available when dealing with the new cluster.

Call a checkpoint on master before pg_rewind.
...
PostgreSQL does not run a checkpoint during promition.
Since pg_rewind relies on the last checkpoint to get the timeline,
there is a short race condition right after the promotion, when
it can get the timeline wrong and fail. We work around this by
calling the checkpoint manually.
Make sure our test configuration does both archive and recovery.
