00a4504cf1 cmd/derpprobe,prober: add ability to perform continuous queuing delay measurements against DERP servers
This new type of probe sends DERP packets sized similarly to CallMeMaybe packets
at a rate of 10 packets per second. It records the round-trip times in a Prometheus
histogram. It also keeps track of how many packets are dropped. Packets that fail to
arrive within 5 seconds are considered dropped.
