Connection drop can crash Spectrum

[Ashoat]

I don't recall the exact context, but I recall from the burn that we would occasionally see a dropped connection cause Spectrum to crash. Ideally, Spectrum would be resilient to dropped connections, and simply keep trying to reconnect until the Beaglebone and LEDscape come back online. The code for this is in OPCAPI.

More context on at least one possible crash: BeginConnect can throw with System.Net.Sockets.SocketException: 'A socket operation was attempted to an unreachable host 192.168.1.69:7890'
