Log IP of Lightstreamer server on connection (beta)

Log the IP address of the Lightstreamer server being connected to by the monitor.

Lightstreamer doesn't expose which IP its connecting to; so this is a quick and dirty solution to get some data until a better solution can be found.

> to work around this we can resolve the Lightstreamer server URL several times and get a dictionary of all it's IP addresses (what is a hacky solution and I'm not sure it will work reliably)
