[pgpool-committers: 4845] pgpool: Add role, replication_delay and last_status_change columns to p

[Tatsuo Ishii]

Add role, replication_delay and last_status_change columns to pgpool_adm's pcp_node_info.

Now the function is sync with show pool_nodes SQL and pcp_node_info
command.  Due to parameter change, I also add upgrade scripts so that
users can migrate from 1.0 to 1.1 using ALTER extension pgpool_adm.

Branch
------
master
