[pgpool-general: 3164] Determining which instance is the master

[John Scalia]

After a couple of rounds of testing this morning, I started wondering which pgpool instance was the master of the cluster. I looked at the pcp commands and I see how to promote one 
instance to master, but nothing really struck me as indicating which instance was currently the master, that is unless I missed seeing that in pcp_node_info. Is there a way to 
determine that programmatically?
