Collect stats to investigate the viability of UDP

connectivity from the browser (first cut). Collect
stats for TCP connectivity also.

- What percentage of users can get a message end-to-end
  to an TCP and UDP server.
- What is the latency for TCP and UDP messages.

Added TCP and UDP echo servers to testserver.py
for unittests.

BUG=82565
TEST=udp tests
