services should not have to specify their host and port

[bhanuvrat]

1. Services defining the HOST and PORT where they are going to run is quite counter intuitive.
   • If there is an entity who knows where each service is going to run, whats the point of having a registry?
2. Registry should detect the IP address from where it gets the registration packet.
   • The HOST address may either be statically specified / detected by socket.gethostbyname(socket.gethostname()) and in both the cases the ip reported may be something behind a NAT and inaccessible for other services / registry itself.
   • And the services can easily listen to all the interfaces by specifying '0.0.0.0' as their host address.

EDIT: After discussion with @nerandell Primary concern is that the service needs to know its own "external" ip address which

• registry can easily find out, based on the connection it gets.
• someone (the devops) needs to hardcode into service's config.json file

@nerandell @kashifrazzaqui views?
