Implement IPP model support in udp_proxy

Implement IPP model support in udp_proxy

This change adds a new "ipp" model in udp_proxy. This model simulates a
WiFi network environment with great variations of latency. The average
rate is roughly rate is about 2mbits/s.

LGTM

(I don't suppose you can add it to tap_proxy.cc too?)

wifi, bad, evil, ipp\n");
ipp is not very descriptive
Is there a better name for it?

This comment should include text like "a challenging interference-heavy WiFi
environment."

Not really planning to add this to tap_proxy yet unless the test team runs
automation on it.
