bind a configured network interface for gossip server endpoint.

[edward-swirldslabs]

Background

Through configuration we need to specify a specific network interface to bind. Many machines will have multiple interfaces and it may be appropriate that only a particular interface should be bound to receive incoming gossip connections.

The configuration should allow the specification of a hostname and port to bind to. The hostname is a string that must be parseable into a Java InetAddress. The port must be an integer value.

Add the new configuration to SocketConfiguration. socket.bindInterfaceHostname and socket.bindInterfacePort.

Acceptance Criteria

• Create SocketFactory unit tests which validates the configuration based successful binding of all 3 local host names 127.0.0.1 (IPV4), localhost (Domain Name) , and 0:0:0:0:0:0:0:1 or ::1 (IPV6) instead of the default 0.0.0.0 which is all interfaces.
• Manually test a local network with the configuration set.
