[pgpool-committers: 4426] pgpool: Fix per node health check parameters ignored.

[Tatsuo Ishii]

Fix per node health check parameters ignored.

Per bug 371. Back patch to the 3.7 stable tree where the feature was
introduced.

Also pgpool_setup is modified to add appropriate per node health check
parameters to pgpool.conf.  This is necessary because
pgpool.conf.sample sets health_check_user0 to 'nobody', which
immediately causes health check failure on DB node 0.
