A UdpClient allows building in a safe immutable way a UDP client that is materialized and connecting when connect() is ultimately called.

Example: 

UdpClient.create()
         .doOnConnect(startMetrics)
         .doOnConnected(startedMetrics)
         .doOnDisconnected(stopMetrics)
         .host("127.0.0.1")
         .port(1234)
         .connect()
         .block()
