Multithreaded UDP socket reading, reuseport for improved performance?

[Dieterbe]

Currently reading from udp socket is slow (golang udp lib not very optimized) and can saturate a CPU core.
Should look into multithreaded udp reading and also reuseport. See https://lwn.net/Articles/542629/

statsd-proxy has REUSE https://github.com/hit9/statsd-proxy i drop less metrics with statsd-proxy + 4x nodejs pids than with statsdaemon latest.

Here is some data on statsd-proxy vs going straight into statsdaemon. The droprate doubles once switching from statsd-proxy -> 4 classic statsd pids to statsdaemon.

10:30 is when cutover occurs for a short test.

It looks like go 1.11 will make this possible soon.
