`statsd` is a daemon written in `node` to gather statistics over UDP. The current test ensures that a port is open, but the basic functionality isn't sufficiently tested. This patch contains the following changes: * Simplified port scanning (`waitForOpenPort` rather than `netcat` magic). * Issue a TCP command to check the health of the `statsd` server. * Simple script to check if `statsd` receives data over UDP and confirms the basic functionality of the TCP interface on `8126` for admin purposes.
