[pgpool-committers: 4919] pgpool: Add support for replication slot to pgpool_setup.

[Tatsuo Ishii]

Add support for replication slot to pgpool_setup.

This eliminates the problem when standby is promoted. When a standby
is promoted, it changes the time line in PITR archive, which will stop
other standby if any because of shared archive directory.
