[pgpool-committers: 1787] pgpool: Add new directive pcp_listen_addresses.

[Tatsuo Ishii]

Add new directive pcp_listen_addresses.

This is similar to listen_addresses, except for pcp process.  Before
pcp listens on all available interfaces including localhost.  Due to
requirement of multitenancy, certain platforms including Openshift
does not allow to listen on localhost. pcp_listen_addresses allows to
specify particlular listen address on such an environment. For
backward compatibilty sake, the default value for pcp_listen_addresses
is '*'. Basic patch was contfibuted by Jeff McCormick. Docs,
pool_status reporting, allowing to specify '', which specifies the
listen address limited to UNIX domain socket and pgpool.conf samples
addition by Tatsuo Ishii.
