[tor-dev] Testing in Tor

I have mixed feelings on this. Stem's tests are chiefly to test Stem,
but the integration tests are for checking how our library interacts
with a live Tor instance. There's a lot of value to Stem for us to
prevent bugs and regression in the Tor controller interface - it helps
Stem's users and prevents us from needing to implement gross hacks
(see for instance the connection.py code for handling #4881).

I'd love for Tor developers to expand Stem's integ tests to better
test's Tor's controller interface. I'm not, however, interested in
having Stem test Tor's other functionality (relaying, hidden service,
etc). I very much agree that down that road lies terrible scope creep.
