Comment:

 This is a start at implementing this feature. I chose to extend the
 bridgestrap API to take requests for Snowflake tests:
 https://dip.torproject.org/cohosh/bridgestrap/tree/ticket/32938

 And made some corresponding changes to proxy-go that will perform the
 throughput test on startup:
 https://github.com/cohosh/snowflake/tree/ticket/32938

 It still needs a lot of work. What I have left to do is:
 - calculate the round trip latency (between sending a message and
 receiving the echo
 - implement this feature for webextension proxies (including a UI)
 - clean up the code and commits a bit
 - perform the test every so often (perhaps 24 hours?)

 This is out of scope for this ticket, but I like the idea in comment:3 of
 using it to tell the proxy how often to poll.
