Hi all,

Following up on Ben's announcement of a "publicly" available DOH server, I
brushed up some of the work I did during IETF 100 Hackathon and pushed the
changes to https://github.com/facebookexperimental/doh-proxy . This is best
effort support, but feel free to file tasks and/or submit PRs.

TL;DR if you have at least python 3.5, you can get the tool from pypi
directly:
```
pip3 install doh-proxy
doh-stub  --listen-port 5553 --domain dns.google.com --remote-address
216.58.193.78 --uri /experimental
```

And the test with `dig @127.0.0.1 -p 5553 ....`

Manu
