[pgpool-committers: 7824] pgpool: Refactor "SHOW pool_pool_pools" and pcp_proc_info.

[Tatsuo Ishii]

Refactor "SHOW pool_pool_pools" and pcp_proc_info.

These commands had many duplicated codes and did not use
infrastructures to make the code shorter. Now they are fixed and it is
much easier to add new data.
