Fix FQDN and port of nodes in peers.json

Pod FQDN was previously invalid, neglecting to have included the service
name. Also the HTTP port (4001) was being listed instead of the Raft
port (4002).

Somehow things worked when both were wrong, presumably by falling back
to DNS-based discovery, but correcting the FQDN issue exposed use of
the wrong port.
