Oops! Georg shouldn't get these notifications. This script is a health check
for my personal relay.

Georg has requested ownership of this service so changing all administrative
notifications to him.

That said, I'll keep package_versions.py since it is unrelated to network
health.

Happy new year! Bumping the dates for 2019...

  % find . -type f -iname '*.py' -exec sed -i 's/-2018/-2019/g' "{}" +;
  % grep -R "# Copyright 2018," ./*

Oops, since we iterate it suppresses errors resulting in a pretty unhelpful
notice...

Now that Stem can download descriptors from an ORPort this health check can be
quite a bit nicer.

Great first use of our new ORPort capabilities. Using it to provide a health
check when my relay's down. If this goes well I'l add it to our Stem tutorials.

Yeah, yeah, I know. Not dirauth related. But hey, there's no reason DocTor
can't provide outage notifications to me as well! :P
