Add Advertise address:port to allow NAT/PAT configuration.
The advertise address:port will be publish in the keeper information to be used by client, sentinel, proxy, ctl or other keeper.
The listening address/port will be used only for postgres instance configuration.

Fix :
  - localhost not need for listenAddress postgres instance
  - check init flag : listenaddress must be explicit, advertise listen address will use listenaddres if not specified
  - check init flag : use specified flag for warn/error message
  - check init flag : don't touch init pgport and just set advertise pg port if not specified
